We want to design a charge amplifier for a piezoelectric sensor that has 500 pF capacitance using a single ideal op-amp. The sensor will be used to detect ceratoid pulses (blood pulses in the wrist); for this application it should allow frequencies only in the range of 0.05 to 100 Hz to pass and should not drift into saturation. Assume no cable capacitance, and sensor resistance is very high. a. Draw the basic circuit indicating all components. b. Specify the value of all components in your design and briefly justify why you have chosen them.
