Patent ID: 6999518

Claim:
A signal receiver for receiving a differential input signal pair through an external differential input terminal pair, comprising: a positive feedback differential amplifier having a differential input terminal pair and a differential output terminal pair; a coupling circuit, coupled to the external differential input terminal pair, the differential input terminal pair and the differential output terminal pair, for coupling the differential input signal pair on the external differential input terminal pair to the differential input terminal pair; and a pre-charger for pre-charging the differential input terminal pair to a predetermined voltage level; wherein the differential input terminal pair is coupled to the external differential input terminal pair before a first time point, the differential input signal pair enters into the differential input terminal pair of the positive feedback differential amplifier via the coupling circuit after the first time point, and the positive feedback differential amplifier is activated to amplify the entered differential input signal pair and outputs to the differential output terminal pair at a second time point a predetermined period after the first time point.
