Title:
VOLTAGE ADJUSTMENT CIRCUIT AND VOLTAGE ADJUSTMENT METHOD FOR CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/166040
Kind Code:
A1
Abstract:
A voltage adjustment circuit and a voltage adjustment method for a circuit, relating to the field of integrated circuits. The voltage adjustment circuit comprises: a first rectifying unit (1), a second rectifying unit (2), a signal control module (3), a switch group (4) and a load (5), wherein the first rectifying unit (1) receives a supply voltage, generates a first voltage based on the supply voltage and outputs the first voltage to the second rectifying unit (2); the second rectifying unit (2) generates a second voltage based on the first voltage and respectively outputs the second voltage to the load (5) and the signal control module (3); and the signal control module (3) generates a switch signal based on the second voltage and outputs the switch signal to the switch group (4), so as to control charging and discharging of an equivalent capacitance of a switch in the switch group (4), thereby adjusting the second voltage. By adjusting the second voltage input to the load (5), a voltage limiting interval is reduced, and the loss in an integrated circuit is reduced.
