Abstract :
A new configuration for realising sinusoidal quadrature oscillators using current follower (CF) is presented. The effects of nonzero-offset voltage and current (at the input and output terminals of a current follower, respectively) on the oscillator are discussed. The resulting oscillating frequency is insensitive to the current tracking error of a CF. Simulation results which agree with theoretical analysis are obtained.
