Ripple rejection of capacitance multiplier when compared to linear regulators
There are some posts and discussions how a circuit popularly called a “capacitance multiplier” could reduce low frequency ripple noise (at 50/60 Hz or 100/120 Hz) and could perform better than common (...

Vdc in ripple factor
V_p(rect) is the rectified unfiltered peak voltage
V_r(pp) is the peak-to-peak voltage after filtering by a capacitor
Here is a picture:
V_r(pp) is given by the expression:
Which I have no problem ...
