Receiver and transceiver for multi-level current-mode signaling

摘要

Provided are a receiver and a transceiver for multi-level current-mode signaling, which together may reduce the number of bus lines and increase a data bandwidth. A transmitter transmits one reference current and a multi-level data current. On the basis of the reference current signal received from the transmitter, a receiver generates plural internal reference currents for determining the multi-level data current received from the transmitter, and converting the received multi-level data current into a data voltage having the desired level corresponding to the data that was transmitted.
