This paper presents a new method for hierarchical characterization of analog integrated circuits. For each circuit class, a fundamental set of performances is defined and extracted topology-independently. A circuit being characterized is decomposed in general subcircuits. Sizing rules of these topology-independent subcircuits are included into the characterization by functional constraints. In ...

Complementary metal-oxide semiconductor (CMOS) operation is very desirable for logic circuit applications as it offers rail-to-rail swing, larger noise margin, and small static power consumption. However, it remains to be a challenging task for nanotube-based devices. Here in this paper, we report our progress on metal contact engineering for n-type nanotube transistors and CMOS integrated circ...

Application specific full custom design integrated circuit is a methodology for making a logic cell, circuit or layout specification. Full custom design circuit is the part of Application specific integrated circuit. A gate array or uncommitted logic array as an approach to the design and manufacture of application specific integrated circuit. It requires custom chip fabrication using a complet...

We numerically investigate the possibility of using Tunnel field-effect transistor (TFET) in a 32 kHz crystal oscillator circuit to reduce power consumption. A simulation using SPICE (Simulation Program with Integrated Circuit Emphasis) is carried out based on a conventional CMOS transistor model. It is shown that the power consumption of TFET is one-tenth that of conventional low-power CMOS.

In this paper, we implement a model of an electric fish, Eigenmannia, that detects frequency differences between the individuals, on analog CMOS circuits. The circuit’s fundamental function is equivalent to a conventional CMOS frequency comparator, although less post-processing is still required. The circuit consists of Pand T-units each of which encodes amplitudes and phases of the monitored e...

The tradition of implementing analogue circuits by means of voltage amplifiers is almost as old as the concept of electronic circuit design. The integrated electronic circuit, however, is a relatively new concept. Furthermore, integrated electronic circuits have significantly different limitations and strengths to the conventional discrete electronic circuits have. Since the active devices in i...

A switched-current integrated circuit, which realizes the chaotic neuron model, is presented. The circuit mainly consists of CMOS inverters that are used as transconductance amplifiers and nonlinear elements. The chip was fabricated using a 1.2 μm HP CMOS process. A single neuron cell occupies only 0.0076 mm2, which represents an area smaller than the one occupied by a standard bonding pad. The...

A novel circuit model based on a trainable memristorcrossbar network integrated with a CMOS circuit for pattern classification and recognition is proposed and analyzed in this paper. The configurable memristors along each column wires of the crossbar are trained by a standard pattern input from the row wires of the crossbar to represent the pattern. After the training, the crossbar network can ...
