Charge amplifier piezo
WebSep 23, 2024 · 1 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: WebI use this piezo only in the flat region of its frequency responce far away from resonance, in which it behaves mostly capacitive. ... (>1 Meg Ohm) b) use a Charge Amplifier made from an opAmp. The output rms of my hydrophone is : 1uV < VoutRms < 50uV and the bandwidth should be from 1Hz to ~200KHz (ultrasonic) with minimal noise. I need to ...
