Abstract:
1. An electric circuit, comprising: a circuit path from a first reference voltage terminal to a second reference voltage terminal, said path comprising means for supplying current, at least one capacitor, first switching means for connecting or disconnecting said at least one capacitor with respect to said means for supplying current, said first switching means having a triggering value; second switching means placed in parallel to said at least one capacitor; and control means for acting on said first and second switching means for controlling charging and discharging of said at least one capacitor, said control means including further means, operable during the charging of said at least one capacitor, for acting on said first switching means for blocking the charging of said at least one capacitor when a voltage value across the at least one capacitor reaches a threshold voltage value, said threshold voltage value being lower than the triggering voltage of said first switching means.
