1) ideal op-amp 理想运算放大器 1. According toideal op-amps characteristics and nodal system of equations, a simulation scheme of the circuit containingideal op-amps based on PSpice is proposed. 据理想运算放大器的控制特性和节点分析法 ,提出含理想运算放大器电路的 PSpice仿真方案 ,详细说明了仿真模...
For example, if the input impedance of an op-amp is low, its input voltage is derived from the input impedance of that op-amp and the output impedance of the preceding device. The low input impedance of an op-amp also affects its feedback loop. If the output impedance of an op...

The ideal op amp has differential inputs, an infinite input impedance, a single-ended output, and infinite gain at all frequencies. The ideal op amp always must be considered as a four-terminal device, the fourth terminal being the return path for the output current. In most designs, it ...
Therefore an ideal op amp, just lying on the table with no power applied, would instantly take a quantum difference between its + and − terminals and amplify it to an infinite voltage output at infinite current. The resulting surge of power would be a sphere of destruction radiating out ...
Op-amps are available as inexpensive self-contained integrated circuits and the detail of what goes on inside the device is rarely of concern. In this chapter, the ideal op-amp, treated as a device, is introduced and many useful circuits based on the ideal op-amp with feedback are ...

If the output impedance of an op-amp is large, its output voltage is derived from the output impedance of that op-amp and the impedance of its load. In typical applications, however, the input impedance of an op-amp is negligibly large compared with the output impedance o...
