FIGURE 1. Simplified op-amp equivalent circuit. The output of the differential amplifier is fed to the circuit's output stage via an offset compensation network which — when the op-amp is suitably powered — causes the op-amp output to center on zero volts when both input terminals are tie...
Op-amp equivalent circuit. If we assume the op-amp has ideal characteristics: 1. Differential gain, A = ∞ (for voltage applied between + and – terminals) 2. Differential voltage, Vd=0 (terminals + and – are at the same voltage) 3. Input resistance, Rin=∞ (zero input current at ...

The equivalent circuit of an op-amp is the circuit where the op-amp parameters are represented in terms of physical components. Such a representation is very helpful for analysis purposes. Below, you can find the equivalent circuit of theop amp. Circuit parameters like the internalresistance, ou...
TI just have a single inductor and a single capacitor for the case of analysing the resistive feedback of an op amp circuit. In this case I found I also needed 1T inductors across the capacitors in the circuit to set the dc conditions or the simulator would get in a real muddle ...

If we assume that the op amp is ideal with infinite gain, a virtual short circuit exists between its two input terminals. Hence the gain of the amplifier is given as: vo/vi= [1 + R2/R1] The gain can be adjusted to unity or more by the proper selection of resistors R2 and R1. ...
Figure 1.16shows an equivalent circuit that illustrates the effect ofoutput impedance. The output circuit is composed of a voltage source and a series resistance (ro). You can think of this as theThevenin equivalentfor the internal circuitry of the op amp. The internal voltage source has a val...
