This paper concerns the design, implementation and subsequent experimental validation of a low-voltage analog CMOS switch based on a gate-bootstrapped method. The main part of the proposed circuit is a new low-voltage and low-stress CMOS clock voltage doubler. Through the use of a dummy switch, the charge injection induced by the bootstrapped switch is greatly reduced resulting in improved samp...

A 64 x 128 real-time infrared (RTIR) complementary metaloxide semiconductor (CMOS)/ silicon-on-insulator (SOI) scene generation integrated circuit (IC) is described. The RTIR IC offers real-time dynamic thermal scene generation. This system is a mixed-mode design, with analog scene information written and stored into a thermal pixel array. The design uses micro-electromechanical sensors (MEMS) ...

The least mean square (LMS) algorithm has practical problems in the analog domain mainly due to dc offset effects. If digital LMS adaptation is used, a digitizer (analog-to-digital converter or comparator) is required for each gradient signal as well as the filter output. Furthermore, in some cases the state signals are not available anywhere in the analog signal path necessitating additional a...

Silicon (Si) based complementary metal-oxide semiconductor (CMOS) technology has been the driving force of the information-technology revolution. However, scaling of CMOS technology as per Moore's law has reached a serious bottleneck. Among the emerging technologies memristive devices can be promising for both memory as well as computing applications. Hybrid CMOS/memristor circuits with CMOL (C...

CMOS was developed as a digitally friendly process. Now, thanks to high levels of system integration and the emergence of SOC (system-on-chip) design, CMOS has also become the process of choice for mixed-signal applications. However, cutting-edge CMOS has limitations in these applications. Process restrictions, inaccurate simulation models, wide parametric variance, and noisy application enviro...

The harmonic oscillator is a truly irreplaceable as well ubiquitous analog integrated circuit. Starting from the basics of its CMOS implementation, we will discuss phase noise in some detail, where intrinsic large-signal operation mandates time-variant analysis. This be followed by survey most popular design techniques enabling low and wide range oscillation frequencies.

Neuromorphic circuits—electronic circuits emulating the functionality of the brain—have teased us for fifty years with their potential for creating autonomous, intelligent machines that can adaptively interact with uncertain and changing environments. Although there are many stumbling blocks to achieving that vision, a primary problem has been the lack of a small, cheap circuit that can emulate...

The purpose of this work was to demonstrate the feasibility of building recurrent artificial neural networks with hybrid complementary metal oxide semiconductor (CMOS)/memristor circuits. To do so, we modeled a Hopfield network implementing an analog-to-digital converter (ADC) with up to 8 bits of precision. Major shortcomings affecting the ADC's precision, such as the non-ideal behavior of CMO...

Driven by the demand of the bioelectronics market, many biosensors need to work in parallel or in a controllable way to achieve complicated biodetections, however the limited scale, speed, cost, complex signal processing, and bulky circuit routing problems prohibit the discrete biosensor solutions (Drummond et al., 2003). Nowaday biosensor are usually integrated on the same substrate to form bi...
