- As we know, front-end of ADC needs an amplifier or balun in generally. Our system need to transfer DC and only drive an ADC, so we design a front-end of ADC by using amplifier. The gain of amplifier is set to 1. Unfortunately, SNR measured with amplifier is lower than SNR under no amplifier.
- Then we consider whether we do not need this amplifier and the input signal is directly transmitted to ADC
I just want to know whether this idea is work.
