Abstract
A current compensation circuit includes a current generating circuit and a signal generator. A first node of the current generating circuit is coupled to an input signal. A second node of the current generating circuit is coupled to a process-dependent current. The current generating circuit is configured to provide a compensation current according to the input signal and the process-dependent current. The signal generator is configured to couple a supply voltage to the first node to provide the input signal. A signal level of the input signal changes in response to a variation in the supply voltage. A supply node of an oscillator is arranged to receive a supply current to drive the oscillator. The current generating circuit is arranged to draw the compensation current from the supply node to compensate for a variation in the supply current generated in response to the variation in the supply voltage.
