Integrated circuit substrate charge pump |
摘要 |
An integrated circuit is disclosed which includes a charge pump adapted for biasing the substrate of a monolithic integrated circuit containing bipolar transistors. An oscillator operating under the control of a control input provides pulsed output signals for driving a diode-capacitor voltage multiplier network which generates a substrate bias voltage. A feedback network including a zener diode senses the substrate voltage, and switching action of the zener diode operates to selectively enable and disable the oscillator for regulating the substrate bias voltage.
