Why Constant Gain or EQ for Robust SI in A Link?

[@abhiruplahiri1]

Very nice video CC. In your experience, did you use PTAT current based analog compensation or also kept tunable R/C (e.g. degeneration resistance and capacitance of conventional equalizer) for continuous background digital tuning with temperature, based on error monitor?

Hi Abhirup, Good question. 😊 Yes, I do, and my ex-colleague kept tunable R/C for background calibration; therefore, I think both approch should be useful & might be needed. Thanks, CC
