Abstract
AbstractA new current-mode sinusoidal quadrature oscillator is presented using current differencing transconductance amplifier (CDTA). This oscillator circuit is designed using one CDTA and two grounded capacitors. By adjusting the bias of CDTA, the oscillation condition and the oscillation frequency can be controlled. The output of the oscillator is current and has high output impedance. It is resistorless and uses grounded capacitors, which ease the IC implementation. PSPICE simulation satisfies the theoretical results.KeywordsQuadrature oscillatorCDTALow component count
