ABSTRACT:
A wide range power supply for integrated circuits includes a voltage-down converter to receive the input supply voltage and generate a controlled low voltage signal. The circuit also includes a voltage-up converter which receives the controlled low voltage signal to generate a high voltage signal for high power circuits. Finally, a substrate bias generator is employed in the circuit to generate a substrate bias signal. Because the low power voltage is controlled, the high power voltage and the substrate bias signal are independent of any variations in input supply voltage. In alternate embodiments, the voltage-up converter or voltage-down converter can be disabled if the external supply voltage is controlled and maintained in at high or low voltage respectfully.
