Title:
DIFFERENTIAL LATCH CIRCUIT, SWITCH DRIVER, AND DIGITAL-TO-ANALOG CONVERSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/041437
Kind Code:
A1
Abstract:
A differential latch circuit, a switch driver, and a digital-to-analog conversion circuit. The differential latch circuit comprises: a first-stage differential latch circuit (I), a second-stage differential inverting circuit (II), and a low-level shift circuit; a pull-up end of a differential positive end of the second-stage differential inverting circuit (II) comprises a first PMOS transistor (M9) and a second PMOS transistor (M10); a pull-down end of the differential positive end of the second-stage differential inverting circuit (II) comprises a third PMOS transistor (M15) and a first NMOS transistor (M11); and the circuit structure at a differential negative end of the first-stage differential latch circuit (I) is symmetrical to the circuit structure at a differential positive end of the first-stage differential latch circuit (I).
