understand what this noise looks like in an amplifier circuit. Amplifier noise can be simplified by modeling it as an external voltage noise e. n(v) on the positive terminal of the amplifier as shown in Figure 2-1. Figure 2-1. Voltage Noise Amplifier voltage noise can be broken down into two main components: flicker noise and broadband noise.

An amplifier is used to increase the amplitude of a signal waveform, without changing other parameters of the waveform such as frequency or wave shape. They are one of the most commonly used circuits in electronics and perform a variety of functions in a great many electronic systems. The general symbol for an amplifier is shown in Fig 1.0.1.
