Abstract
A receiver front-end includes a first peaking gain stage configured to amplify a received differential pair of signals received on an input differential pair of nodes. The first peaking gain stage has a first frequency response including a first peak gain at or near a carrier frequency in a first pass band. The first peak gain occurs just prior to a first cutoff frequency. A second peaking gain stage is configured to amplify a differential pair of signals generated by the first peaking gain stage. The second peaking gain stage has a high input impedance and a second frequency response including a second peak gain at or near the carrier frequency in a second pass band. The second peak gain occurs just prior to a second cutoff frequency. The first peaking gain stage and the second peaking gain stage have a cascaded peak gain at or near the carrier frequency.
