Title:
LEAKAGE COMPENSATION DYNAMIC REGISTER, DATA COMPUTING UNIT, CHIP, COMPUTING POWER BOARD, AND COMPUTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/063052
Kind Code:
A1
Abstract:
A leakage compensation dynamic register, a data computing unit, a chip, a computing power board, and a computing apparatus. The leakage compensation dynamic register comprises: an input terminal (D), an output terminal (Q), a clock signal terminal (CKN, CKP), and an analog switch unit (201); a data latch unit (202) latching data under control of a clock signal; and an output drive unit (203) used to perform phase inversion on and output data received from the data latch unit (202). The analog switch unit (201), the data latch unit (202), and the output drive unit (203) are sequentially connected between the input terminal (D) and the output terminal (Q) in series. The analog switch unit (201) and the data latch unit (202) has a node (S0) therebetween. The leakage compensation dynamic register further comprises a leakage compensation unit (204) electrically connected between the node (S0) and the output terminal (Q). The invention achieves effective compensation for a dynamic leakage current of the node (S0), thereby improving data security and accuracy.
