charge amplifier

I have been trying to replicate the bode plot from this article: https://www.allaboutcircuits.com/technical-articles/how-to-design-charge-amplifiers-piezoelectric-sensors I have attached my ltspice plot (white) and their plot (black). Any input welcome.

Hello everyone! :) I am having difficulty in understanding a concept since I am not in the electrical field. I am working on a project to measure the dynamic force on a surface using embedded PVDF transducers. Based on the theories I studied so far, if I connect this PVDF to the charge...

Hi there, Recently, I have designed a new charge amplifier than can be used to implement a precision and low-cost interface for piezoelectric sensors. I have published an article about the novel proposed circuit in IEEE Sensors Journal. ( A brief information about the new proposed circuit has...
