A switched-capacitor Wien bridge oscillator and its automatic gain controller are discussed for low-frequency generation. The dc voltage Vs related to the amplitude of oscillation is obtained from the voltage differences in the frequency-determining arm. Theoretical analysis of the ripples in Vs is reported.
