Hi Arash, Nice to meet you and I'm glad you like it. :)

Thank you very much for sharing these valuable information. It is more helpful than basic design information. The PI circuit has two stacked devices in series with resistor. For high-speed design, such as 112GBPS PAM,4, what is the size of resistor, capacitor, I and power supply? Thx

Hi S. Yan, You're very welcome. Nice to meet you. I'm glad that's helpful. 😊 The supply was 0.75V in 5nm. I don't have the exact value of resistor, capacitor, but you should be able to size it based on your slew rate, headroom limitation & noise. Therefore, usually, that highly depends on all the specifications, which might be different from different designs.
