Document Type and Number:
WIPO Patent Application WO/2021/036034
Kind Code:
A1
Abstract:
Disclosed are a multi-stage drive data transmission circuit and data transmission method. The multi-stage drive data transmission circuit comprises: a first drive module and a second drive module. The first drive module comprises a first signal generation unit and a first tri-state driver. The second drive module comprises a second tri-state driver. The first input end of the second tri-state driver is coupled to the output end of the first tri-state driver. The first signal generation unit comprises a first input end, a second input end, and an output end. The output end of the first signal generation unit is coupled to the second input end of the first tri-state driver. The first signal generation unit is used for receiving a first signal by means of the first input end thereof, and receiving a first feedback signal, from the second drive module, of the first signal, by means of the second input end thereof, generating, according to the first signal and the first feedback signal, a first control signal having an effective signal width greater than that of the first signal, and providing the first control signal for the first tri-state driver.
