A new switched-capacitor (SC) oscillator is described. The oscillator is easily modified to be either voltage controlled or digitally programmed. Although the oscillator is practical only when its oscillating frequency is less than about 1/25 the clock frequency (because of the excess phase jitter that develops at higher ratios), it is useful in a number of… (More)
