Hello,
I am attaching my LTspice simulation file for the AD828,
I want to model my source to AD8428 as a variable impedance source (capacitance of 66 nF) that varies its impedance from 500KHz at 1 Hz to 10 Ohms to 30KHz with variable capacitance and with various sine wave amplitudes.
Also when I run an ac analysis on this file, It simply shows -210 dB which cannot be so.
Can you help me reduce the offset down to 0V.
Hi Sumeet6 ,
I can only help with the AC result. Your problem there is you have no input into the op amps, as V6 has no AC value for .ac analysis.
