Abstract
This paper presents a new current-mode quadrature oscillator employing only a single current-controlled current conveyor transconductance amplifier, two grounded capacitors and one grounded resistor. The circuit is beneficial to monolithic integrated circuit implementation by using grounded capacitors. The oscillation condition and the oscillation frequency can be independently controlled. The oscillation frequency can also be controlled electronically by adjusting the bias currents. The realized of the circuit provides explicit quadrature voltage and current outputs. Simulation results that confirm the theoretical predictions are also given. © 2011 IEEE.
