This is the specifications that must be met: "Design a charge amplifier for a piezoelectric sensor that has 500 pF capacitance. It should pass frequencies from 0.05 to 100 Hz so that it can detect carotid pulses, and it should not drift into saturation."
This is the values that I was able to solve:
The resulting circuit looks like this:
I based it on a circuit I saw on the internet but I'm not sure. Was I able to do it correctly?
