There have recently been more and more reports on CMOS integrated circuits operating at terahertz (≥ 0.1THz) frequencies. However, design environments and techniques are not as well established as for RF CMOS circuits. This paper reviews recent progress made by the authors in terahertz CMOS design for low-power and high-speed wireless communication, including device characterization and modelin...

Computer-aided design (CAD) tools are frequently employed to verify the design objectives before the fabrication of an integrated circuit. An important circuit parameter that requires accurate characterization is the power consumption due to the strict constraints on the acceptable power envelope of integrated systems. Circuit simulators typically provide built-in functions to measure the power...

Abstract  In his paper a new current-controlled conveyor (CCCII) in CMOS technology is presented. It features, low supply voltage (±0.7), low power consumption, low circuit complexity, rail to rail operation and wide range parasitic resistance ( ). The circuit has been successfully employed in a multifunction biquad filter. Simulation results by HSPICE show high performance of the circuit and c...

The explosive development of wireless communication services creates a demand for more flexible and cost-effective communication systems that offer higher data rates. The obvious trend towards small-size and ultra low power systems, in combination with the ever increasing number of applications integrated in a single portable device, tightens the design constraints at hardware and software leve...

A compact complementary metal-oxide semiconductor (CMOS) circuit for depressing synapses is designed for demonstrating applications of spiking neural networks for contrast-invariant pattern classification and synchrony detection. Although the unit circuit consists of only five minimum-sized transistors, they emulate fundamental properties of depressing synapses. The results of the operations ar...

The concept of a manufacturable technology that can provide parallel optical interconnects directly to a VLSI circuit, proposed over 15 years ago in [1], now appears to be a reality. One such optoelectronic-VLSI (OE-VLSI) technology is based on the hybrid flip-chip area-bonding of GaAs/AlGaAs Multiple-Quantum Well (MQW) electro-absorption modulator devices directly onto active silicon CMOS circ...

The continuous increase of integration densities in Complementary Metal–Oxide–Semiconductor (CMOS) technology has driven the rapid growth of very large scale integrated (VLSI) circuit for today's high-tech electronics industries from consumer products to telecommunications and computers. As CMOS technologies are scaled down into the nanometer range, analog and mixed integrated circuit (IC) desi...

defuzzifier circuit is one of the most important parts of fuzzy logic controllers that determine the output accuracy. the center of gravity method (cog) is one of the most accurate methods that so far been presented for defuzzification. in this paper, a simple algorithm is presented to generate triangular output membership functions in the mamdani method using the multiplier/divider circuit and...

This paper presents noise characterization of a CMOS 0.6-μm image sensors system. The integrated readout circuit adaptability allows measuring the photocurrent magnitude of each pixel in charge integration mode or in transimpedance mode. In order to find the minimum detectable signal of this system and to identify the main dominant noise sources, an accurate noise analysis is performed under da...

The future of integrated circuits will include the integration of high performance III-V electronic and/or opto-electronic devices with standard Si CMOS to create to a new class of highly integrated, high performance, ‘intelligent’, mixed signal and RF circuits. While traditional hybrid approaches, such as wire bonded or flip chip multi-chip assemblies may provide short term solutions, the vari...
