ABSTRACT:
A pulse generator circuit for applying a pulse signal to the input source electrode of a charge coupled device (CCD) having a "fill and spill" input operation, includes a voltage reference circuit for generating the "fill" voltage level of the pulse signal and a capacitive element circuit for boosting the voltage level of the pulse signal to a "spill" voltage level which exceeds the operating potential applied to the pulse generating circuit. With this type of pulse generating circuit the operating potential applied to the CCD and its support circuitry (including the pulse generator circuit) can be reduced in order to lower system power consumption while ensuring proper "spill" operation.
