Abstract

See full text

A data register unit, a SAR ADC and an electronic device are disclosed. The data register unit comprises: a first high-speed flip-flop; a second high-speed flip-flop; and a first logic gate, wherein the first high-speed flip-flop and the second high-speed flip-flop comprise a high-speed flip-flop circuit respectively, which comprises: a first PMOS transistor, a first NMOS transistor, an inverter and a logic gate. The data register unit of the present disclosure is composed of a high-speed flip-flop circuit with a very simple structure and suitable for fast operation. In a further embodiment, the high-speed flip-flop circuit can combine the bit pulse to realize the capacitor switching based on the comparison result. This increases the operation speed of the SAR ADC while significantly reducing the number of transistors required to implement the EMCS logic.
