Input voltage of the filter in Pspice simulation

[rinaishlene]

Hi,

I would like to for ask for any opinion regarding what kind of input that I should trigger (either Vsin or VAC)to generate the frequency response of the BIQUAD FILTER?
And how much the value of the input voltage that should be used?

A typical biquad filter is realised using 3 stages viz., a leaky integrator followed by another non-leaky integrator and finally an inverter. If you are designing using opamp such as 741, then you should see select the input as a sine wave with amplitude such that none of these stages are saturated. Then you can carry out an ac sweep analysis.

Best of luck.
