Abstract
A buffer stage for amplifying a clock signal generated by a current controlled oscillator that receives a first current at a first supply voltage from a first current source. The buffer stage comprises an input terminal configured to receive the clock signal; an output terminal configured to output a buffered signal; at least one buffer, coupled between the input and output terminal, configured to receive a second current at a second supply voltage and buffer the clock signal to generate the buffered signal; a clamping circuit that receives the first current and the second current, and generates a first supply voltage and a second supply voltage. The clamping circuit clamps the second supply voltage equal to the first supply voltage.
