Abstract:
1. An electronic device including a set of functional blocks, and a biasing block for generating a set of bias voltages to supply operating power to the functional blocks, comprising: a holding block coupled between the biasing block and the functional blocks for providing each bias voltage to a corresponding at least one functional block, for each bias voltage the holding block including a capacitive element for storing the bias voltage, and a switch element switchable between an accumulation condition in which the bias voltage is provided from the biasing block to the capacitive element and to the corresponding at least one functional block, and a release condition in which the capacitive element is isolated from the biasing block and provides the bias voltage from the capacitive element to the corresponding at least one functional block, and a control block for alternately switching the switch elements between the accumulation condition and the release condition, wherein the holding block supplies operating power to the functional blocks in the accumulation condition and in the release condition and wherein the control block includes a generator block for receiving a reference voltage included among the bias voltages from the biasing block and for generating a further reference voltage from the reference voltage, an oscillator block for receiving the further reference voltage from the generator block and for generating a periodic clock signal with a period depending on the further reference voltage, and a state machine for receiving the clock signal from the oscillator block and for generating a control signal according to the period of the clock signal, all the switch elements being controlled by the control signal.
