ABSTRACT:
Voltage generator circuitry uses a first capacitor (Q1) that is selectively isolated from an output terminal (26) by a first transistor (Q4). The gate of Q4 is coupled to a circuit terminal (16) which is capacitively coupled via second capacitor (Q5) to the output terminal (20) of a delay gate (28). The first capacitor (Q1) is charged to a potential level near or at that of a power supply (VDD) and then a positive going waveform applied to Q1 causes it to be charged to a potential level above VDD. Terminal 16 is charged by the positive going waveform to a value at or near VDD and then it is increased in potential after the delay time of the delay gate (28). This enables (biases on) Q4 and allows the output terminal (26) to assume a potential level greater than that of VDD.
