A New Approach for Low Voltage CMOS based on Current-controlled Conveyors

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...

New Oscillator Topologies Using Inverting Second-Generation Current Conveyors

In this work, new oscillator topologies based on a recently introduced active element, namely inverting second-generation current conveyor, are presented. This recently introduced unity gain based active element is suitable for integrated circuit realization and can easily be implemented with CMOS technology. Considering this fact, basic oscillator topologies employing a single, two and three c...

Design of second-generation current conveyors employing bacterial foraging optimization

The present paper deals with the optimal sizing of CMOS positive second-generation current conveyors (CCII+) employing an optimization algorithm. A contemporary non-gradient stochastic optimization algorithm, called bacterial foraging optimization (BFO) algorithm, has been employed to obtain the optimal physical dimensions of the constituent PMOS and NMOS transistors of the CCII+. The optimizat...

On Multi-port Current Conveyors

A new terminology (order, kind, class) and the classification and definition of multi-port current conveyors are given. The generalized current conveyor is defined as a tool for synthesis. Several autonomous circuits containing multi-port conveyors are presented. The design of ARC oscillators and second-order filters based on the given autonomous networks is described in this paper.
