This paper presents an electronically controllable grounded capacitor quadrature oscillator using single multiple-output current controlled current differencing transconductance amplifier (MO-CCCDTA) as an active element. The proposed circuit employs a single MOCCCDTA, two grounded capacitors and one grounded resistor and offers the advantages of (i) independent control of condition of oscillation (CO) and frequency of oscillation (FO), and (ii) low active and passive sensitivities. The workability of proposed configuration has been demonstrated by PSPICE simulation.
