摘要： A system includes a Trans-Impedance Amplifier (TIA) to amplify an input signal from an optical module. The TIA is to interface with the optical module via a transmission line and a reference ground routed next to the transmission line. The transmission line and reference ground are to thermally isolate the TIA from the optical module. An impedance control is to cause an impedance adjuster to match an input impedance of the TIA to a transmission line impedance.

摘要： A receiver includes a front-end amplifier, a sampler, and a decision-feedback equalizer. The front-end amplifier provides for amplifying a received input signal to yield an amplified input signal. The sampler provides for sampling the amplified input signal so as to yield a sampler output signal. The sampler output signal is a function of the amplified input signal and a reference signal coupled to a reference input of the sampler. The decision feedback equalizer provides for adjusting the reference signal as a function of feedback based at least in part on the sampler output signal.
