Abstract :
A Wien bridge oscillator using switched capacitors (SC) and its automatic gain controller were tested. Over the frequency range from 10/sup 2/ Hz to 10 /spl mu/Hz, the oscillation was stable and the frequency was proportional to the clock frequency of SC. The distortion factor and the rise time were also discussed.<>
