Patent ID: 7786764

Claim:
A signal receiver, comprising: a first-stage circuit, having a first input end, a second input end, a first output end, and a second output end, the first input end receiving a reference voltage and the second input end receiving an input signal; a second-stage circuit, having a first input end, a second input end, and at least one output end, the first input end of the second-stage circuit coupled to the first output end of the first-stage circuit, the second input end of the second-stage circuit coupled to the second output end of the first-stage circuit, and the at least one output end used for outputting an output signal; a current compensation circuit, coupled to the first input end of the second-stage circuit, for dynamically providing a compensation current to the first input end of the second-stage circuit in response to a first biasing voltage, so as to stabilize a voltage level at the first input end of the second-stage circuit; and a biasing circuit, coupled to the first-stage circuit and the current compensation circuit, for biasing the first-stage circuit and the current compensation circuit in response to the reference voltage and for setting the first biasing voltage of the current compensation circuit.
