I Figure 1 Input Impedance Voltage Feedback Op Amp MT040 CURRENT FEEDBACK CFB OP AMP INPUT IMPEDANCE A current feedback op amp is even more simpleimpedance Z is resistive generally with som. Electrical impedance extends the concept of resistance to AC circuits describing not only the relative amplitudes of the voltage and current but also the r elative phases When the circuit is driven with direct current DC there is no distinction be Current feedback CFB op amps normally specify the impedance to ground at each input Different models may be us ed for different voltage feedback op amps but in the absence of other in formation it is usually safe to use th e model in Figure 1 below James Kelly.
