Abstract :
A sine wave switched-capacitor (SC) oscillator based on feedback SC BPF oscillator is proposed. The advantage of this technique is high stability, constant amplitude at wide frequency range and suitability for amplitude control by output forced response technique. In addition, frequency tuning can be adjusted by clock control, without effect on stability. The experimental results conforming the validity of the theory are also presented
