Abstract

A signal transceiver circuit, a method of operating a signal transmitting circuit, and a method of setting a delay circuit are provided. The signal transceiver circuit is used to send an output signal and receive an input signal, and includes: a delay circuit for delaying a first clock to generate a second clock; a first digital-to-analog converter (DAC) for converting a first digital signal into the output signal according to the first clock; a second DAC for converting the first digital signal into an echo cancellation signal according to the second clock; an analog front-end circuit for receiving the input signal and the echo cancellation signal and generating an analog signal; and an analog-to-digital converter (ADC) for converting the analog signal into a second digital signal.
