System, method, and apparatus for analog signal conditioning of high-speed data streams

摘要

A device includes circuitry configured to receive a signal burst, apply one or more filters to the signal burst based to achieve a predetermined image rejection rate, apply at least one harmonic rejection mode to the signal burst, and amplify the signal burst based on a gain partitioning determination.

1. A device comprising:
circuitry configured to
attenuate a signal burst based on a first predetermined gain step,reject one or more harmonic frequencies of the signal burst at a harmonic rejection mixer based on predetermined harmonic rejection modes,filter an output of the harmonic rejection mixer based on a predetermined image rejection rate,amplify the output of the harmonic rejection mixer via a programmable gain operational amplifier having a first differential input of a differential input pair corresponding to at least one switch of one or more switch sets associated with a second predetermined gain step and a second differential input of the differential input pair connected to ground, andoutput an enhanced signal burst to at least one analog-to-digital converter (ADC).
