dc.description.abstractThis article deals with the configuration of an electronically tunable quadrature oscillator using voltage differencing gain amplifiers (VDGAs) as active devices. The circuit employs a single grounded resistor and two grounded capacitors, which is advantageous from the monolithic integration point of view. It serves as an alternative application of VDGA device and provides the advantages of availability of two quadrature output voltages, independent control of oscillation condition and oscillation frequency by electronic means through the external biasing currents, and good various sensitivity performances. The results from PSPICE simulation program are included that demonstrate the working of the proposed circuit.
