What is the purpose of source follower?

An important aspect of the source follower is to provide power or current gain. That is to say drive a lower resistance (impedance) load from a higher resistance (impedance) stage. Thus it is instructive to measure the source follower output impedance.

How to Calculate Break Frequency of Source Follower?

Break Frequency of Source Follower calculator uses Break Frequency = 1/sqrt(Constant C) to calculate the Break Frequency, The Break frequency of source follower formula is defined as a boundary in a system's frequency response at which energy flowing through the system begins to be reduced (attenuated or reflected) rather than passing through. Break Frequency is denoted by f_b symbol.

How to calculate Break Frequency of Source Follower using this online calculator? To use this online calculator for Break Frequency of Source Follower, enter Constant C (c) and hit the calculate button.
