Abstract
A Biphase Mark Coding (BMC) transceiver is provided. In the BMC transceiver, an operational amplifier operating in a time division multiplexing manner is used. The operational amplifier is configured as a unity gain buffer, and it is determined whether the BMC transceiver operates as a transmitter or a receiver by selecting different input switches and output switches. In a transmitting mode, a bias current of an input differential pair transistor of the operational amplifier is changed, to change a slew rate, so as to obtain an output waveform with adjustable rising/falling edges of the transmitter.
