Abstract
In this paper, a new quadrature oscillator employing two dual output second-generation current conveyors (DO-CCIIs), two resistors and two grounded capacitors is proposed. The proposed quadrature oscillator has only resistors but no capacitors connected in series to [Formula: see text] terminals of the DO-CCIIs; thus, it can be operated at high frequencies. It can be tuned electronically by replacing dual output second-generation current controlled current conveyors instead of DO-CCIIs and removing both resistors. It can provide two output currents in opposite sign. Nevertheless, its resonance frequency can be simultaneously controlled by two resistors. Also, a dual output differential voltage current conveyor (DO-DVCC) based quadrature oscillator which employs a canonical number of only grounded passive components is proposed. A number of simulation results based on SPICE program and an experimental test result are included to exhibit performance, workability and effectiveness of the proposed quadrature oscillators.
