Nvis 6578 Operational Amplifier Lab is a unique product covering the important concepts, theory and applications of operational amplifier circuits. An operational amplifier is a direct-coupled high gain amplifier usually consisting of one or more differential amplifiers followed by a level translator and an output stage. The operational amplifier is a device that can be used to amplify DC as well as AC input signals. It was originally designed for computing mathematical functions such as Addition, Subtraction, Multiplication and Integration. Using Nvis 6578 students can perform experiments of OP-AMP circuits like Inverting amplifier, Non Inverting amplifier, Adder, Subtractor, Differentiator, Integrator, Comparator, etc. Nvis 6578 has on-board Resistors, Capacitors and Potentiometers of different values.

Cascode amplifier is a two stage circuit consisting of a transconductance amplifier followed by a buffer amplifier. The word “cascode” was originated from the phrase “cascade to cathode”. This circuit have a lot of advantages over the single stage amplifier like, better input output isolation, better gain, improved bandwidth, higher input impedance, higher output impedance, better stability, higher slew rate etc. The reason behind the increase in bandwidth is the reduction of Miller effect. Cascode amplifier is generally constructed using FET ( field effect transistor) or BJT ( bipolar junction transistor). One stage will be usually wired in common sourcecommon emitter mode and the other stage will be wired in common base common emitter mode.
