Abstract
A power source circuit for an oscillator is provided comprising a multiplexer, a plurality of transmission gates, a plurality of resistors, a current source circuit, and an output circuit. The multiplexer inputs a digital signal and outputs one or more control signals. The transmission gates is individually coupled to the multiplexer and receives the one or more control signals, wherein each of the plurality of transmission gates are turned on or off according to the one or more control signals. The plurality of resistors is coupled in series and individually coupled to the plurality of transmission gates. The current source circuit is coupled to the plurality of resistors and provides a current source. The output circuit is coupled to the current source and provides output power for the oscillator according to the current source and the operation of the transmission gates.
