Abstract
The present disclosure provides a semiconductor device. The semiconductor device includes a difference-expanding device and a receiver. The difference-expanding device receives an input signal having voltage levels representing logical states, and converts the input signal to a processed signal by changing, based on the voltage levels, degrees in conduction of the difference-expanding device. The receiver receives the processed signal from the difference-expanding device, and determines the logical states of the input signal based on the processed signal.

A semiconductor device, comprising:
- a difference-expanding device configured to receive a bias and an input signal having a first voltage level representing a first logical state and a second voltage level representing a second logical state, and convert the input signal to a processed signal by changing, based on a voltage difference between the bias and the input signal, degrees in conduction of the difference-expanding device;
- and
- a receiver configured to receive the processed signal from the difference-expanding device, and determine the input signal represents a logically low state or a logically high state based on the processed signal.
A semiconductor device, comprising:
- a difference-expanding device configured to convert an input signal to a processed signal, the difference-expanding device including:
- a resistor;
- and
