Title:
VOLTAGE SUPPLY CIRCUIT AND HIGH FREQUENCY CIRCUIT MODULE
Document Type and Number:
WIPO Patent Application WO/2019/009087
Kind Code:
A1
Abstract:
This voltage supply circuit is provided with: a level shifter (12) for switching and outputting voltage of two voltage input units; a charge pump (11N) for transforming the voltage of an input power supply and applying the transformed voltage to the level shifter (12); and a charge pump control circuit, wherein the voltage supply circuit controls supplying and stopping the supply of a predetermined voltage to a voltage supply target circuit (RF switch 20). When a state where voltage is stopped being supplied to the voltage supply target circuit (RF switch 20) is represented as an OFF mode, and a state where a predetermined voltage is being supplied is represented as an ON mode, the charge pump control circuit continuously operates the charge pump (11N) in the ON mode and periodically intermittently operates the same in the OFF mode.
