Polyphase filters (PPFs) are an efficient solution for high accuracy quadrature generation in radio frequency (RF) CMOS design. Although there are some guidelines for design of RF CMOS PPFs, they give too much freedom. With layout considerations, optimization of RF CMOS PPFs cannot be reached by using analytical calculations because of many constraints and tradeoffs in the design. Thus, in desi...

Analog-centric RFCMOS technology has played an important role in motivating the change of technology from conventional discrete device technology or bipolar IC technology to CMOS technology. However it introduces many problems such as poor performance, susceptibility to PVT fluctuation, and cost increase with technology scaling. The most important advantage of CMOS technology compared with lega...

This paper presents an excitatory CMOS neuron oscillator circuit design, which can synchronize two neuron-bursting patterns. The excitatory CMOS neuron oscillator is composed of CMOS neurons and CMOS excitatory synapses. And the neurons and synapses are connected into a close loop. The CMOS neuron is based on the Hindmarsh-Rose (HR) neuron model and excitatory synapse is based on the chemical s...

Abstract: Dynamic Domino logic circuits are widely used in modern digital VLSI circuits. Because it is simple to implement, low cost designs in CMOS Domino logic are presented. Compared to static CMOS logic, dynamic logic offers good performance. Wide fan-in logic such as domino circuits is used in high-performance applications. Domino gates typically consume higher dynamic switching and leakag...

A new generation method to implement CMOS floating resistors is presented. The generation method depends on the linearization of the differential current of two matched NMOS transistors in two alternative configurations. The CMOS floating resistors implemented are based on using MOS transistors operating in the saturation region with their sources connected to their substrates. New CMOS floatin...

Abstract—The Spatially Modulated Light CMOS detector (SML CMOS detector) removes the slow part of the current response of a traditional CMOS photodetector, by using the difference between the signals of an immediate and a deferred detector. This slow part of the current response limits the maximum frequency of a photodetector in the conventional CMOS technology to a few MHz. Experimental eviden...

Substantial increase in gate and sub-threshold leakage of complementary metal-oxide-semiconductor (CMOS) devices is making it extremely challenging to achieve energy-efficient designs while continuing their scaling at the same pace as in the past few decades. Designers constantly sacrifice higher levels of performance to limit the ever-increasing leakage power consumption. One possible solution...
