Abstract
Provided are a differential latch circuit, a switch driver, and a digital-to-analog conversion circuit. The differential latch circuit includes: a first-stage differential latch circuit (I), a second-stage differential inverter circuit (II), and a low-level shift circuit, a pull-up terminal of a differential positive terminal of the second-stage differential inverter circuit (II) includes a first P-Channel Metal-Oxide-Semiconductor (PMOS) transistor (M) and a second PMOS transistor (M), a pull-down terminal of the differential positive terminal of the second-stage differential inverter circuit (II) includes a third PMOS transistor (M) and a first N-Channel Metal-Oxide-Semiconductor (NMOS) transistor (M), and a circuit structure of a differential negative terminal of the first-stage differential latch circuit (I) is symmetrical to a circuit structure of a differential positive terminal of the first-stage differential latch circuit (I).
