Abstract: A method for detecting a null current condition in a PWM driven inductor connected between a voltage source node and a second circuit node of a line for outputting current to a load includes generating a derivative signal by time differentiating a voltage on the second node. The method further includes monitoring an instant when the derivative signal becomes negative, and signaling verification of the null current condition each time the derivative signal becomes negative.

Abstract: A method and a circuit are for regulating the source terminal voltage of a non-volatile memory cell during the cell programming and/or reading phases. The method includes a phase of locally regulating the voltage value and includes comparing the source current of the cell array with a reference current. A fraction of the source current is converted to a voltage and compared with a voltage generated from a memory cell acting as a reference and being programmed to the distribution with the highest current levels. The comparison may be used for controlling a current generator to inject, into the source terminal, the current necessary to keep the predetermined voltage thereof at a constant value.
