(Sample) Op-amp circuit analysis using a transfer function - Result -


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.

Op-amp circuit:

Z1 Z2


(Sample) Transfer function from the Op-amp circuit:

G(s)= s2+1111000s+1010000000
s2+111000s+10000000

Pole(s)

p = -14.349939362259[Hz]
      |p|= 14.349939362259[Hz]
p = -17651.848743838[Hz]
      |p|= 17651.848743838[Hz]

Zero(s)

z = -144.80489759888[Hz]
      |z|= 144.80489759888[Hz]
z = -176676.3368775[Hz]
      |z|= 176676.3368775[Hz]

Final value of the step response (on the condition that the system converged when t goes to infinity)
