S11 for bandpass filter

engrvip


I am designing a bandpass filter using active inductor as shown in attached schematic and had a query in this regard.

Since this is a BPF I am interested in seeing its S21 response. But for that ckt input and output impedance should match with input and output port impedance so that S11 and S22 are low.

But since I am in initial phase of my design I dont want to spend too much time in input matching and just want to see S21 response of my filter. For that I want to minimize S11 and S22.

How can I achieve this input and output matching in spectreRF so as to see optimum s21 response of my filter ? Can load/source pull analysis be of any help to achieve this requirement ?

Regards

Vipul
