Signal receiver and signal transmission apparatus

摘要

A signal receiver includes first and second bias circuits that receive an input signal and convert the input signal to respective first and second bias signals. The signal receiver also includes a first inverter comprising a PMOS device and an NMOS device, each device has a source, a drain, and a gate. When the voltage magnitude of the first bias signal is smaller than that of the input signal, the gate of the PMOS device is coupled to the first bias signal and the gate of the NMOS device is coupled to the input signal. When the voltage magnitude of the first bias signal is greater than that of the input signal, the gate of the NMOS device is coupled to the first bias signal and the gate of the PMOS device is coupled to the input signal.
