Abstract
A transmitter circuit applicable to a digital isolator is provided, adapted to receive a data input signal and coupled to an isolation barrier, developing a receiver input signal to a receiver circuit for generating a data output signal. The transmitter circuit generates a transmitter output signal in response to a rising edge and falling edge of the data input signal, and includes a rising and falling converter for outputting a converted data input signal according to the rising edge and falling edge of the data input signal, a delay and logic unit for receiving the converted data input signal and generating a carrier signal, and an AND gate receiving the converted data input signal and the carrier signal, and outputting the transmitter output signal. Since a number of pulses of the carrier signal is limited and definite, the present invention achieves to reduce power consumption and electromagnetic interferences effectively.
