Title:
FLIP-FLOP CIRCUIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/060469
Kind Code:
A1
Abstract:
A flip-flop circuit (100) and an electronic device. The flip-flop circuit (100) comprises a plurality of signal inverting elements (1), wherein a substrate of a P-type transistor (MP) of each signal inverting element (1) is correspondingly connected to a bias voltage providing circuit (2). The bias voltage providing circuit (2) is used for responding to an input end signal (Vin) of the corresponding signal inverting element (1), providing a first substrate bias voltage (V1) for the P-type transistor (MP) when the P-type transistor (MP) in the signal inverting element (1) is turned on, and providing a second substrate bias voltage (V2) for the P-type transistor (MP) when the P-type transistor (MP) in the signal inverting element (1) is not turned on, wherein the first substrate bias voltage (V1) is less than the second substrate bias voltage (V2) and is greater than a PN junction turn-on voltage. The signal inverting element (1) is used for inverting the input end signal (Vin). The flip-flop circuit (100) can repair a signal timing deviation caused by element aging.
