  • Abstract
    A type of RC-active Wien-bridge oscillator is proposed whose oscillation frequency is independent of the time constants of the op amps used in the design and is determined only by passive components. Other important effects such as the influence of parasitic poles and nonlinearities in the stability of the system are also analyzed. Experimental results are given, showing close agreement with theoretical predictions
