Abstract
A control circuit for a clock electrode of an integrated circuit includes two semiconductor switches (TP, TN) which are controllable from a clock pulse generator (CG) and via which semiconductor switches one of two direct voltages (+Va, oV) is periodically applied to a clock electrode (E), constituting a capacitive load, of an integrated circuit (IC). In order to reduce the energy dissipation, the clock electrode is connected to ground via a series arrangement (LC) of an inductance (L) and a capacitance (C). The clock pulse generator triggers the switches (TP, TN) in a manner such that the switches are successively conductive with an interval thereinbetween in which both switches are non-conductive. As a result, a resonant circuit (L, C, CE) consisting of the inductance (L), the capacitance (C) and the clock electrode capacitance (CE) is active during the in between intervals.
