Abstract :
A biquad active-RC oscillator is described and a linear analysis given which shows that harmonics injected within the feedback loop are multiplied by a factor which is inversely proportional to the effective open-loop Q-factor Q0. Experimental results show that distortion is low at high Q0 values even when saturated operation of the main gain-producing op amp is allowed
