Patent ID: 8350598

Claim:
A multi-stage receiver for generating differential signals, comprising: an input stage configured to provide a first signal and a second signal, and the second signal being an inverted signal of the first signal; an intermediate stage coupled to the input stage, the intermediate stage comprising: a first amplifying circuit having a positive input terminal configured to receive the first signal, a negative input terminal configured to receive the second signal, and an output terminal configured to generate a first skewed signal; and a second amplifying circuit having a positive input terminal configured to receive the second signal, a negative input terminal configured to receive the first signal, and an output terminal configured to generate a second skewed signal; and an output stage coupled to the intermediate stage and configured to generate the differential signals, the output stage having a first input terminal configured to receive the first skewed signal, a second input terminal configured to receive the second skewed signal, a first output terminal configured to generate a first output signal according to the first and second skewed signals, and a second output terminal configured to generate a second output signal according to the first and second skewed signals.
