Abstract: An oscillating analog signal includes a succession of dampened oscillations. That oscillating analog signal is conditioned to generate an output signal including only oscillations of the oscillating analog signal which have an amplitude smaller than a first threshold. The output signal is then processed by a processing unit, where the first threshold is compatible with a maximum level of voltage tolerable by the processing unit.

Abstract: A circuit has a supply line, a reference line and circuitry coupled between the supply line and the reference line. The circuitry outputs a regulated voltage and a measurement voltage. An analog-to-digital converter (ADC) generates a digital signal indicative of variations of potential differences between the supply line and the reference line based on the regulated voltage and the measurement voltage. The generated digital signal may be used to control the circuit.
