Abstract: A voltage regulator is embedded in a circuit intermediate a first node (coupled to a battery) and a second node (supplying power to an external memory). The voltage regulator is activatable in a first mode of operation for startup during which an voltage is applied to the second node that increases towards a supply threshold. In response to the voltage at the second node reaching the supply threshold, the voltage regulator transitions to a second mode of operation where a programmable regulated voltage (higher than the supply threshold) is applied to the second node. In response to receipt of a low-power operation request, a first high-drive regulator circuitry is deactivated and a second low-power regulator circuitry is activated to provide a third mode of operation at low power.

Abstract: A system for interfacing an LC sensor includes a starter configured to selectively start an oscillation of the LC sensor. The system also includes an analog peak detector configured to determine a signal (Vpeak) being indicative of a peak voltage of the oscillation of the LC sensor and a detector configured to determine a state of the LC sensor as a function of the signal (Vpeak) determined by the analog peak detector.
