• Electronics Engineering » Notes » Operational Amplifier 1. The Op Amp is a widely used amplifier abstraction that forms the foundations of much of electronic circuit design. Op Amp devices are constructed using primitive elements such as transistors and resistors. 2. The Op Amp is a four-ported device. The ports include an input port with terminals usually labeled v+ and v− , an output port with one terminal labeled vo, and the other being ground, a positive power supply port with a +VS voltage applied with respect to ground, and a negative power supply port with a −VS voltage applied with respect to ground. Although the ground terminal is not explicitly shown in the Op Amp symbol, it is very much a part of all Op Amp circuits. 3. The Op Amp behaves like a voltage-dependent voltage source. Its input output relationship can can be expressed mathematically as vo=A(v+−v−) where A is a large number called the open loop gain of the amplifier. In most practical Op Amp applications, A is treated as infinity. 4. Most useful Op Amp circuits are built using the negative feedback connection, in which a portion of the output signal of the Op Amp is fed back to the v− input of the Op Amp. Examples of Op Amp circuits…
