Title:
LEVEL SHIFTING CIRCUIT, CONTROL METHOD THEREFOR, AND DRIVING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/142745
Kind Code:
A1
Abstract:
Provided in the present application are a level shifting circuit, a control method therefor, and a driving circuit, related to the technical field of level shifting. The level shifting circuit comprises a first input end, a first output end, an alternating-current coupling subcircuit, and a positive feedback subcircuit. The alternating-current coupling subcircuit comprises a first coupling input end and a first coupling output end. The first coupling input end is connected to the first input end. The first coupling output end is connected to a first node. The alternating-current coupling subcircuit is used for the alternating-current coupling of a signal of the first coupling input end to the first coupling output end. The positive feedback subcircuit comprises a first feedback input end and a first feedback output end. The first feedback input end and the first feedback output end are connected to the first node. The first node is connected to the first output end. The level shifting circuit is applicable in level shifting of a full frequency band or a wide frequency band.
