HI,

I am designing a demodulator for RFID tags.
But the demodulator is performing the action when the input voltage amplitude is 1v.

I want the demodulator to perform its operation for very low input voltages.
Shall I use a gain boosting circuit before the demodulator?

What are the pros and cons for the above logic?

Thanks!!

Is the design logically correct or feasible, if I use a gain boosting circuit before doing demodulation?

I am comparing the design if I use only a demodulator.
