Abstract
A device for generating a supply or bias voltage and a clock signal for a synchronous digital circuit is provided. The device includes an oscillator circuit comprising a propagation path representative of a critical path of the circuit and which varies with a supply or bias voltage to the oscillator, and outputting a periodic signal, the frequency whereof depends on the propagation path delay; a resistive element; a switched capacitor coupled to the output of the oscillator such that the switching frequency thereof corresponds to the frequency of the periodic signal or to a multiple or divisor of this frequency; and an amplifier circuit outputting, from an output coupled to a power supply input or bias input of the oscillator, a voltage, the amplitude whereof is representative of a difference between the resistance R and the equivalent resistance of the switched capacitor.
