Abstract

In this paper, four new first order voltage mode cascadable allpass sections are proposed using single active element and three grounded passive components, ideal for IC implementation. The active element used is a fully differential current conveyor. All the proposed circuit possess high input and low output impedance feature which is a desirable feature for voltagemode circuits. Nonideality aspects and parasitic effects are also given. As an application, a multiphase oscillator is designed. The proposed circuits are verified through PSPICE simulation results using TSMC 0.35 µm CMOS parameters.
