Analysis of op amp circuits.

Lastly, this app note covers a noise model used by op amp manufacturers to measure the noise characteristics of a device. There are two components of this model. A voltage source is placed in series with positive input and noiseless op amp. A current source is placed between each input and ground. Both of these interact with a noiseless op amp.In the circuit below, a potentiometer of total resistance R is redrawn as two resistors R1 and R2. This equivalent circuit is valid as long as R = R1 + R2 R = R 1 + R 2. Let's assume it is a linear potentiometer. This means that, when the wiper (node B): is turned "all the way to the left" (the wiper is at A), then R1 = 0 R 1 = 0 and R2 = R R 2 ...Analysis of Circuits Containing Ideal Op Amps.
