Abstract: A digital circuit comprises a plurality of functional circuits and a finite state machine. Each functional circuit comprises a digital macro, a resistance control device and at least one device with capacitance. The digital macro is coupled to a ground. The resistance control device is electrically connected between the digital macro and an always-on power mesh. The at least one device with capacitance is electrically connected between the resistance control device and the ground. The finite state machine is electrically connected to the resistance control device, and is configured to adjust the resistance of the resistance control device.

Abstract: A signal generator includes a main ring oscillator and a first ring oscillator. The main ring oscillator is supplied by a power voltage, and is configured to generate an output oscillation signal. The main ring oscillator is coupled through a power mesh to the power voltage. The first ring oscillator is supplied by the power voltage. The first ring oscillator is similar or identical to the main ring oscillator. The first ring oscillator is coupled through the power mesh to the power voltage. The first ring oscillator is used to calibrate a frequency of the output oscillation signal.
