Abstract
A clocking signal drive circuit supplies at least one clocking signal in a charge transfer device which has a plurality of successive capacitive storage elements for sequentially holding a charge level representing a time sampled input signal, with each of the capacitive storage elements having a clocking electrode for receiving one of a plurality of clocking signals so that the charge level representing the time sampled input signal is transferred from one to another of the capacitive storage means in succession in response to the clocking signals. The clocking signal drive circuit includes a clocking signal generator having an output at which the generator provides a clocking control signal, and a pair of complementary transistors each having first, second, and control electrodes, with the control electrode of the complementary transistors being connected together and to the output of the clocking signal generator and the first electrodes of the complementary transistors being connected together and to the clocking electrode of at least one of the capacitive storage elements. In one embodiment of the invention the clocking signal drive circuit functions as an output device for de…
