The second approximation is that the inputs of the op amp draw no current. Using Kirchoff's current law and the assumption that no current flows into the op amp gives: R2 v v R1 − −v v in = out − −. Recognizing that (from the first assumption above) gives the gain ...
Web1.2 Ideal Op Amp Model. The Thevenin amplifier model shown in Figure 1-1 is redrawn in Figure 1-2 showing standard op amp notation. An op amp is a differential to single-ended amplifier. It amplifies the voltage difference, V. d = V. p - V. n, on the input port and produces a voltage, V. o, on the output port that is referenced to ground. www ...
