Operational Transresistance Amplifier-Based Multiphase Sinusoidal Oscillators
Multiphase sinusoidal oscillator circuits are presented which utilize Operational Whips Transresistance Amplifier (OTRA) as the active element.The first circuit produces n odd-phase oscillations of equal amplitudes and equally spaced in phase.The second circuit is capable of producing n odd- or even- phase oscillations equally spaced in phase.An al
