ABSTRACT:
A supply voltage originating from the charge present across a buffer capacitance connected in parallel with a logic gate including CMOS transistors is present across this gate. The loss of charge occurring when the capacitively loaded gate output is charged must be replenished. To this end there is provided a small direct current source feeding the buffer capacitance.
