Hi,
I have designed the strain measurement circuit with instrumentation amplifier and RC low pass filter.
Gain =10, Vsin = 2 v, input Freq = 2 kHz, cut off frequency fc = 15.9 kHz. The circuit is working efficiently until the frequency of the input is varied to 6 kHz but beyond these value the output is unpredictable that is amplitude is decreasing.
Please find the attachment of the circuit screen shot and Lt Spice model is attached.
Thanks and Regards,
Richi Nixon V
