Electronically tunable MOSFET-C mixed-mode quadrature oscillator

Abstract

A new mixed-mode quadrature oscillator circuit using two multi-output current controlled conveyors (MOCCCIIs) and two grounded capacitors is presented. In the proposed circuit, four quadrature current-mode signals are available at high impedance nodes. The oscillation conditions and oscillation frequencies are orthogonally (or independently) controllable… (More)
