Hello,
I am supposed to design a circuit where i can determine the change in Variable capacitance Cx by a change in DC output voltage at the output by keeping the reference capacitance constant. I tried using a lot of different filters but the output of the filter does not follow the output of the multiplier I am using. I am posting my circuit file (created in LTSpice) along with the paper i am referring. Any help is much appreciated.
Thank you.
