An accelerometer with a charge sensitivity of 83 pC/g and a capacitance of 1000pF is connected
to a voltage follower with an input connector capacitance of 15pF (in parallel with the cable
capacitance), a 10,000pF blocking capacitor and a 100M? resistance. A 3m long cable with a
capacitance of 312pF connects the accelerometer and the voltage follower. Determine:
1. the schematic of the instrument.
2. the instrument’s voltage sensitivity in mV/g.
3. the minimum sampling frequency required to sample the data.
4.The gain required in order that the instrument can measure the acceleration from 0.01g to 1g using a 12-bit ±5V A/D converter.
