What Does a Neutralizing Circuit Do in an RF Amplifier? Working Principle Explained

Achieving ideal performance in the field of radio frequency (RF) amplifiers is a challenging task. RF signals must be amplified without distortion or feedback to preserve the signal’s quality as they cover a broad range of frequencies.  Engineers use a…

What Is the Difference Between Differential Gain and Common-Mode Gain? Detailed Comparison

The key difference between differential gain and common-mode gain is that differential gain refers to the gain applied to the difference between two input signals in a differential amplifier whereas Common-mode gain refers to the gain applied to signals that…

Why Is Open Loop Gain Infinite in Op-Amp? A comprehensive Guide

The open-loop gain of an operational amplifier (op-amp) is considered infinite for ideal cases due to the input signal (differential or single) being slightly greater than zero.  In practical terms, it is typically considered very high. Open-Loop Configuration in Op-Amp…

What Is the Difference Between LM339 and LM324 Op-Amps? A Comparison Guide

The LM339 is a quad-voltage comparator, which means it contains four separate comparators. The LM324 is a quad operational amplifier (op-amp) with four amplifiers. While it is not explicitly designed as a comparator, it can still be used for basic…
