The differential amplifier is intended to respond only to the difference between the two input voltages, v1 and v2. However, in a practical op-amp the output depends to some degree on the sum of these inputs. For example, if both inputs are equal, the output voltage should ideally be ...
An op-amp is a differential amplifier which has a high i/p impedance, high differential-mode gain, and low o/p impedance. When the negative feedback is applied to this circuit, expected and stable gain can be built. Usually, some types of differential amplifier comprise various simpler diffe...

Using the proposed transconductor, an op amp and a differential difference amplifier (DDA) were implemented in a 1.2-/spl mu/m CMOS process. The transconductor has a total harmonic distortion (THD) of less than -60 dB for an input swing of 400 mV at 10 kHz. The op amp and the DDA...
version of an integrated,fully differential amplifier. Q1 and Q2 are the input differ-ential pair. In a standard op amp, output current is taken from only one side of the input differential pair and is used to develop a single-ended output voltage. In a fully differ-ential amplifier, ...

Instrumentation amplifier. A typical differential amplifier has a positive and a negative input terminal and an output terminal. The schematic symbol unfortunately looks a lot like that for an op-amp, sometimes leading to a bit of confusion. Some differential amplifiers have an additional reference ...

Figure 1. A Simple Differential Amplifier This circuit amplifies the difference between input signals v1(t) and v2(t). It can be analysed using the Principle of Superposition by summing the contributions to vo(t) from v1(t) and v2(t) when acting independent of each other.Consider the ...
