Title: Single Ended Switched Capacitor Opamp to Differential Conversion Post by repah on Nov 28th, 2018, 4:31pm Hello, I designed a single ended opamp sample/hold switched capacitor amplifier with sample capacitors and switches. I want to convert it to a differential opamp. What do I do to the current, the sampling caps, size of switches, load capacitance ? Can I just scale these from single ended design ? Also, add Common Mode Feedback. Is this correct ? Is this correct ? Did I forget anything ? Thank you. |
