CFOA Based Second Order Low Frequency Sensitive Sinusoidal Oscillator
In this paper, a second order sinusoidal oscillator (SO) has been presented using Current Feedback Operational Amplifiers (CFOA) as active element. It uses five resistors and two capacitors. It exhibits complete independent tuning between frequency of oscillation and condition of oscillation through resistors. The sensitivity analysis has been carried out and it is observed that it exhibits low FO sensitivity to various circuit parameters. PSPICE simulations are used to check the efficacy of the proposed circuit and the simulation results are in close proximity with theoretical calculations. The observed total harmonic distortion (THD) is lower than 2.5%.
