Abstract
The disclosure provides a bias voltage calibration circuit adapted for a signal receiving device. The bias voltage calibration circuit includes a reference voltage generator, a voltage-current converter, and a bias current generator. The reference voltage generator receives a voltage adjustment signal, and adjusts a voltage value of a generated reference voltage according to the voltage adjustment signal. The voltage-current converter is coupled to the reference voltage generator, and converts the reference voltage to generate a reference current. The bias current generator generates a plurality of bias currents according to the reference current, and provides the bias current to an equalization circuit of the signal receiving device in a calibration mode.
