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...
Oprational Amplifier<What are Opamps and Comparators?> What are Opamps? Opamps (operational amplifiers) are differential amplifiers that amplify the differential voltage between the positive(+)/ negative(-) input pins and are characterized by high input resistance, low output resistance, and high ...
Basically an op-amp is a differential amplifier which amplifies difference between voltages V1 and V2 provided at its inputs. There are three conditions and based on these appropriate output is produced as mentioned below. • If V2>V1, then Vo is positive ...

The top of Figure 5 shows the collector, or drain currents, of various differential amplifier types vs. differential input voltage. We simulate a simple bipolar pair, a translinear circuit that we will call clever bipolar, a subthreshold (that is, very large) MOS differential pair, a bipola...
In this cir- cuit, the FDA is used as an attenuator in a manner similar to using an inverting op amp, as described in Part 1 for the differential bipolar signal. The design equations are the same as in Part 1, except that the input impedance is reduced by approximately half. Thus, ...
Op-Amp Issues Q.Why are there so many different types of operational amplifier? A. Because there are so many parameters that are important in different applications, and because it is impossible to optimize all of them at once. Op amps may be selected for speed, for noise (voltage, current...
