Original Abstract
The main aim of this work is to demonstrate the use of electronically controlled second-generation current conveyor in providing electronic control to the condition of oscillation (CO) of a new active RC sinusoidal oscillator. Electronic control of the CO, which is independently set and does not affect the oscillation frequency, is enabled by the use of an auxiliary amplitude control loop to regulate the amplitude and provide very good total harmonic distortion performance. The proposed oscillator employs only one standard second-generation current conveyor, one electronically controlled second-generation current conveyor, five passive elements and is capable to provide three voltage outputs having phase shifts 45 and 90 degrees, if specific design requirements are fulfilled. Similar simple types of oscillators do not provide such features. Non-ideal analysis of the circuit has been also carried out and the proposed oscillator has been verified by both PSpice simulations and experimental measurements using commercially available integrated circuits.
