Abstract
A signal transmission circuit includes N signal transmission paths, a boost control module and a first feedback module; the signal transmission path includes two signal transmission terminals and a path switch connected between the two signal transmission terminals; the first feedback module is configured to feed back a voltage to be superimposed to the boost control module, the voltage to be superimposed is matched to the maximum voltage among voltages of the M signal transmission terminals; the boost control module is configured to boost the input voltage and output a target signal through a third terminal of the boost control module to drive the path switch into a first state by using the target signal when the input voltage is at a high level, where a voltage of the target signal is adapted to the sum of a boosted voltage of the input voltage and the voltage to be superimposed.
