Op-amp circuit analysis using a transfer function

This tool determine the transfer function from a inverting / non-inverting amplifier circuit. The transfer function is simulated frequency analysis and transient analysis on graphs, showing Bode diagram, Nyquist diagram, Impulse response and Step response.

Select the following circuit:
Inverting amplifier
Non-inverting amplifier
Select Z1
Select Z2
Z1 Z2
R1= Ω
R2= Ω
C1= F
R3= Ω
R4= Ω
C3= F
C4= F

p:pico, n:nano, u:micro, k:kilo, M:mega
