Abstract
A multi-stage receiver comprises an input stage, an intermediate stage, and an output stage. The input stage is configured to provide a first signal and a second signal. The intermediate stage is coupled to the input stage and comprises a first amplifying circuit and a second amplifying circuit. Positive and negative input terminals of the first amplifying circuit receive the first signal and the second signal, respectively. Positive and negative input terminals of the second amplifying circuit receive the second signal and the first signal, respectively. The output stage is coupled to the intermediate stage and configured to generate low-skewed differential signals according to output signals of the intermediate stage.
Claims11
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.
