Abstract: A circuit includes combinational circuit and sequential circuit elements coupled thereto. The circuit includes a multiplexor coupled to the combinational and sequential circuit elements, and a system register is coupled to the multiplexor. At least one portion of the combinational and sequential circuit elements is configured to selectively switch to operate as a random access memory.

Abstract: A method of interfacing a LC sensor with a control unit is provided. The control unit may include first and second contacts, where the LC sensor is connected between the first and the second contact. A capacitor is connected between the first contact and a ground. To start the oscillation of the LC sensor, the method may include during a first phase, connecting the first contact to a supply voltage and placing the second contact in a high impedance state such that the capacitor is charged through the supply voltage. During a second phase, the first contact may be placed in a high impedance state, and the second contact connected to the ground such that the capacitor transfers charge towards the LC sensor. During a third phase, the first contact and the second contact may be placed in a high impedance state so the LC sensor is able to oscillate.

Abstract: In accordance with an embodiment, a method includes: producing a set of delayed replicas of a reference clock signal, wherein delayed replicas in the set of delayed replicas have respective signal edges delayed in time by a mutual time delay therebetween; producing a set of edge detecting signals comprising edge detecting signals indicative of respective distances of edges of delayed replicas in the set of delayed replicas from an edge of a clock signal having a clock period; selecting based on edge detecting signals in the set of edge detecting signals a delayed replica in the set of delayed replicas having a distance from the clock signal edge that is shorter than the distance from the clock signal edge of any other delayed replica in the set of delayed replicas.

Abstract: A clock generator includes a microcontroller unit calibrated by aligning at subsequent calibration times a frequency of a first clock with respect to the frequency of a second clock having a higher frequency accuracy than the first clock, with the frequency of the first clock varying between subsequent calibration times. The frequency of the first clock is aligned to a frequency which is offset by a certain amount with respect to the frequency of the second clock to counter frequency error which may accumulate over time due to the variation in the frequency of the first clock.

Abstract: A method of interfacing an LC sensor with a control unit is described. The control unit may include first and second contacts, and the LC sensor may be connected between the first and second contacts. The method may include starting the oscillation of the LC sensor, and monitoring the voltage at the second contact, in which the voltage at the second contact corresponds to the sum of the voltage at the first contact and the voltage at the LC sensor. The voltage at the first contact may be varied such that the voltage at the second contact does not exceed an upper voltage threshold and does not fall below a lower voltage threshold.
