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...

With the rapid development of computers and communications, more and more chips are required to have small size, low-power and high performance. Digital filter is one of the basic building blocks used for implementation in Very Large Scale Integration (VLSI) of mixed-signal circuits. This paper presents a design of decimation filter used for digital filtering. It consists of Cascode Integrated ...

High precision temperature switches are required in a large number of today’s ICs for monitoring the die temperature. Upon detection of a too high die temperature measures to prevent over-heating of the chip can be taken; these measures include reducing the performance of large digital processors by setting lower supply voltages and/or lower clock frequencies. For this type of temperature detec...

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...

This study presents a performance analysis of low power CMOS Integrated “Current Conveyor Ion Sensitive Field Effect transistor” (CC-ISFET). The study’s main focus is on simulation of power and performance analysis of ISFET device, which is used for water quality monitoring. This approach can improve calibration of device to a fairly wide range without the use of a high speed digital processor....

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 ...

Two architectures for a 1-V, 10-bit 200-kS/s successive approximation analog-to-digital converter (ADC) implemented in a standard CMOS 0.18 μm digital process are presented. A track-andhold circuit based on a novel implementation of the bootstrapped low-voltage analog CMOS switch with a novel rail-to-rail trackand-latch comparator circuit is described. A pMOS-only ladder containing a rail-to-ra...
