Electronics Tutorial - A look at the Capacitance Multiplier

FesZ Electronics

Why people recommend it

FesZ Electronics explains the capacitance multiplier using LTspice simulations, cited as a clear account of how a cheap circuit cuts supply ripple and noise.

Watch for: Best with some transistor circuit knowledge already in place

In their words

Now I have taken the trouble to watch two movies on YouTube (the Dave's movie suggested by C36 and the FesZ's movie) and I saw that I had basically guessed the idea.

Update: The functional improvements of using this resistor are didactically explained by ‘FesZ Electronics’ video here with simulations in LTspice.
