Special Issue Information

Dear Colleagues,

We are inviting the wide community of practicing electronic engineers and scientists working in industry, government, and academia to participate in the Special Issue on Analog Microelectronic Circuit Design and Applications. The purpose of this Special Issue is to provide a collection of papers covering the broad spectrum of analog electronics, namely: monolithic device models, high performance analog circuits, radio-frequency communications and PLL circuits, and data converters. The goal is to provide the most up-to-date information in the field.

Over the years, the fundamentals of analog microelectronic circuit designs have evolved to include a wide range of topics and a broad range of practices. To encompass such a wide range of knowledge, this Issue should focus on the key concepts, models, and equations that enable design engineers to analyze, design, and predict the behaviour of analog large-scale circuits and systems. While design formulas and tables are welcomed, emphasis should be placed on the key concepts and theories underlying the processes.

This Special Issue’s papers should stress the fundamental theories behind professional applications and demonstrate examples to reinforce this point. Extensive development of theory and details of proofs should be omitted.

The compilation of this Issue will not been possible without the dedication and efforts of all the contributing authors. I wish to thank all of them in advance.

Topics of interest will include:

  • CMOS device models
  • Operational amplifiers
  • Low-dropout regulators
  • Sinusoidal oscillators
  • Wideband amplifiers
  • Analog phase-locked loop circuits
  • Radio-frequency receivers
  • Digital-to-analog converters

A high-speed programmable frequency divider for a Ka-band phase-locked loop (PLL)-type frequency synthesizer system is presented and fabricated in 90 nm CMOS technology.

A high-speed programmable frequency divider for a Ka-band phase-locked loop (PLL)-type frequency synthesizer system is presented and fabricated in 90 nm CMOS technology. It consists mainly of a divided-by-8/9 dual-modulus prescaler (DMP) and pulse swallow counters. An active-inductor-based source-coupled logic (SCL) D flip-flop (DFF) and the “OR” gate are used in the DMP in order to promote its locking range and operation frequency. The measured operation frequency range of the improved programmable frequency divider covers from 6 to 20 GHz with a low phase noise of less than −136 dBc/Hz at a 1 MHz offset of output signals, an optimum sensitivity of −27 dBm at 15 GHz, and a low power consumption of 9.1 mW.

The recording of neural signals with small monolithically integrated amplifiers is of high interest in research as well as in commercial applications, where it is common to acquire 100 or more channels in parallel. This paper reviews the recent developments in low-noise biomedical amplifier design based on CMOS technology, including lateral bipolar devices. Seven major circuit topology categories are identified and analyzed on a per-channel basis in terms of their noise-efficiency factor (NEF), input-referred absolute noise, current consumption, and area. A historical trend towards lower NEF is observed whilst absolute noise power and current consumption exhibit a widespread over more than five orders of magnitude. The performance of lateral bipolar transistors as amplifier input devices is examined by transistor-level simulations and measurements from five different prototype designs fabricated in 180 nm and 350 nm CMOS technology. The lowest measured noise floor is 9.9 nV/√Hz with a 10 µA bias current, which results in a NEF of 1.2. Full article

Nowadays, signal lights are made using light-emitting diode arrays (LEDs). These devices are extremely energy efficient and have a very long lifetime. Unfortunately, especially for yellow/amber LEDs, the intensity of the light is closely related to the junction temperature. This makes it difficult to design signal lights to be used in naval, road, railway, and aeronautical sectors, capable of fully respecting national and international regulations. Furthermore, the limitations prescribed by the standards must be respected in a wide range of temperature variations. In other words, in the signaling apparatuses, a system that varies the light intensity emitted according to the operating temperature is useful/necessary. In this paper, we propose a simple and effective solution. In order to adjust the intensity of the light emitted by the LEDs, we use an LED identical to those used to emit light as a temperature sensor. The proposed system was created and tested in the laboratory. As the same device as the ones to be controlled is used as the temperature sensor, the system is very stable and easy to set up.

This paper deals with a single-stage single-ended inverter-based Operational Transconductance Amplifiers (OTA) with improved composite transistors for ultra-low-voltage supplies, while maintaining a small-area, high power-efficiency and low output signal distortion. The improved composite transistor is a combination of the conventional composite transistor and forward-body-biasing to further increase voltage gain. The impact of the proposed technique on performance is demonstrated through post-layout simulations referring to the TSMC 180 nm technology process. The proposed OTA achieves 54 dB differential voltage gain, 210 Hz gain–bandwidth product for a 10 pF capacitive load, with a power consumption of 273 pW with a 0.3 V power supply, and occupies an area of 1026 μm2. For a 0.6 V voltage supply, the proposed OTA improves its voltage gain to 73 dB, and achieves a 15 kHz gain–bandwidth product with a power consumption of 41 nW. Full article

This article presents a wideband reconfigurable integrated low-pass filter (LPF) for 5G NR compatible software-defined radio (SDR) solutions. The filter uses Active-RC topology to achieve high linearity performance. Its bandwidth can be tuned from 2.5 MHz to 200 MHz, which corresponds to a tuning ratio of 92.8. The order of the filter can be changed between the 2nd, 4th, or 6th order; it has built-in process, voltage, and temperature (PVT) compensation with a tuning range of ±42%; and power management features for optimization of the filter performance across its entire range of bandwidth tuning. Across its entire order, bandwidth, and power configuration range, the filter achieves in-band input-referred third-order intercept point (IIP3) between 32.7 dBm and 45.8 dBm, spurious free dynamic range (SFDR) between 63.6 dB and 79.5 dB, 1 dB compression point (P1dB) between 9.9 dBm and 14.1 dBm, total harmonic distortion (THD) between −85.6 dB and −64.5 dB, noise figure (NF) between 25.9 dB and 31.8 dB and power dissipation between 1.19 mW and 73.4 mW. The LPF was designed and verified using 65 nm CMOS process; it occupies a 0.429 mm2 area of silicon and uses a 1.2 V supply. Full article

In this study, a novel IR projector driver that can minimize nonuniformity in electric circuits, using a dual-current-programming structure, is proposed to generate high-quality infrared (IR) scenes for accurate sensor evaluation. Unlike the conventional current-mode structure, the proposed system reduces pixel-to-pixel nonuniformity by assigning two roles (data sampling and current driving) to a single transistor. A prototype of the proposed circuit was designed and fabricated using the SK-Hynix 0.18 µm CMOS process, and its performance was analyzed using post-layout simulation data. It was verified that nonuniformity, which is defined as the standard deviation divided by the mean radiance, could be reduced from 21% to less than 0.1%. Full article
