Abstract
A bias circuitry includes a simulation circuit and a level shifter circuit. The simulation circuit is configured to simulate circuit architecture of a processing circuitry, in which the processing circuitry is biased by a bias signal, in order to generate output signals according to input signals. The level shifter circuit is configured to increase a voltage difference between a first node and a second node of the simulation circuit, in which the first node is for tracking an output common mode voltage of the output signals, and the second node is for outputting the bias signal.
