Title:
ELECTRONIC DEVICE AND DRIVING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/173636
Kind Code:
A1
Abstract:
An electronic device and a driving method therefor. The electronic device comprises a sense amplifier (SA) and a voltage regulation circuit (6). The sense amplifier (SA) comprises a first P-type transistor (PM1), a second P-type transistor (PM2), a first N-type transistor (NM1), a second N-type transistor (NM2), and a control circuit (1), wherein the control circuit (1) is connected to a third node (ISB), a fourth node (IST), a preset voltage terminal (VB), and a first control signal terminal (OC) and is used for connecting the preset voltage terminal (VB) to the third node (ISB) and the fourth node (IST) in response to a signal of the first control signal terminal (OC); and the voltage regulation circuit (6) is connected to the preset voltage terminal (VB) and an regulating signal terminal (TRIM) and is used for inputting a preset voltage signal to the preset voltage terminal (VB) according to the regulating signal of the regulating signal terminal (TRIM). The electronic device can write a preset voltage signal of a suitable size to the sense amplifier (SA) by means of the voltage regulation circuit (6), such that the sense amplifier (SA) has an appropriate voltage difference between an offset cancellation phase bit line (BLT) and a complementary bit line (BLB).
