A Novel Square Wave Generator Based on the Translinear Circuit Scheme of Second Generation Current Controlled Current Conveyor-CCCII

Abstract

A robust square wave generator employing a sole capacitor and two resistors has been presented in this study. Low power and popular translinear circuit scheme of Second generation current controlled current conveyor-CCCII has been taken as an active element to implement the proposed square wave generator. CCCII inhibits promising features like availability of three mutually independently and electronically adjustable parameters corresponding transconductance (gm), intrinsic resistance (r) of the current input terminal and current gain between two terminals) that are very prevalent for control applications accepted currently. The operating frequency of the proposed model has been analyzed with respect to the passive components present there, with no exposure of output signals to the thermal voltage (VT). Electrical/Device properties (like Noise, Threshold, area etc.) of the proposed circuit have also been discussed in this work. The simulation work was carried out on Synopsis Hspice tool (v-2008.03) from Avant. Satisfying results with anticipation of theoretical and simulated results, including precision (consistency assessment) with Pareto analysis (Ist order Best Test flavored by Decision making analysis) were observed during the study. The 45nm BSIM CMOS modelling parameters were adopted to prove the theory. The elementary purpose of using such parameters is to maximize the circuit drive and lowering the leakage current. Another purpose of using these modelling parameters is to enhance the realization of the proposed circuit in the custom Integrated circuit(IC) form, from a Standard local foundry. Maximum power consumption of the circuit is 600 micro Watt, with 2V rail to rail operating voltages
