Circuit and method for data transmission

A circuit for data transmission, comprising:

• a signal generator;
• a first signal synthesizer;
• and
• a voltage comparator;
• wherein
• an output terminal of the signal generator is connected to an input terminal of the first signal synthesizer;
• an output terminal of the first signal synthesizer is connected to an input terminal of the voltage comparator;
• a clock terminal of the signal generator and a clock terminal of the first signal synthesizer are configured to receive a clock signal externally inputted;
• the signal generator is configured to receive at least one data signal from a transmitter, generate a pulse signal based on the clock signal, the data signal and a first predetermined rule, and transmit the pulse signal to the first signal synthesizer;
• the first signal synthesizer is configured to synthesize the pulse signal and the clock signal to obtain a synthesized signal, and transmit the synthesized signal to the voltage comparator;
• and
• the voltage comparator is configured to obtain the data signal based on the synthesized signal.
