Abstract
A receiver amplifier and also a receiver equalizer is provided for a three-level signaling system. The receiver amplifier includes a single current source that drives a current into node shared by three transistors arranged in parallel. A trio of input signals corresponds to the three transistors on a one-to-one basis. Each input signal drives the gate of its corresponding transistor. In addition, each transistor produces a corresponding output voltage at a terminal coupled to a resistor. The receiver equalizer includes three transistors and three corresponding equalizing pairs of a resistor and a capacitor. A terminal for the capacitor and for the resistor in each equalizing pair connects to a terminal of the corresponding transistor.
