This article showcases the advantages of an op amp loop-stability analysis method that I use myself and recommend to others. This method looks at the behavior and rate of closure of the open-loop gain ...

Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

Amplifiers in cascode Configuration and their variations are generally used to overcome Miller Capacitance, improve the small signal gain and output impedance. Increasing number of transistors in ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

Operational Trans-conductance Amplifier (OTA) is a fundamental building block of analog circuits and systems. OTA has been used to implement many kinds of analog circuits such as; opamps, data ...
