This book provides an invaluable reference to Piezoelectric Accelerometers with Integral Electronics (IEPE). It describes the design and performance parameters of IEPE accelerometers and their key elements, PE transducers and FET-input amplifiers. Coverage includes recently designed, low-noise and high temperature IEPE accelerometers.

Mo doc covid 19The IEPE circuit a fixed positive DC voltage as its power source, this is referred to as the ‘compliance voltage’, and gives what is known as a ‘single ended’ output where the output signal is always a positive voltage.

This is the schematic of the circuit we will build, shown below: The formula to find the frequency cutoff point of an RC circuit is, frequency= 1/2πRC. Doing the math, with the values shown above, we get a frequency of, frequency= 1/2πRC = 1/2(3.14)(1KΩ)(10nF)= 15,923 Hz, which is approximately 15.9KHz.
