In this article for audioXpress, Bill Reeve helps us to make sense of a misunderstood circuit. A capacitance multiplier is useful as a power supply low-pass filter. It is commonly said that, like Miller capacitance, the capacitor’s value in this circuit is “multiplied” by the transistor gain (β) to lower the filter’s pole frequency.

The AD834 is a true linear multiplier with a transfer function of • Ω • = 1V 250 V V I x y OUT Eq. 3 . Its X and Y offsets are trimmed to 500 µV (3 mV max), and it may be used in a wide variety of applications including multipliers (broadband and narrowband), squarers, frequency doublers, and high frequency power measurement circuits.
The "sound" of a mosfet in capacitance multiplier | diyAudio
https://www.diyaudio.com/community/threads/the-sound-of-a-mosfet-in-capacitance-multiplier.327471/
Hi, I'm using a capacitance multiplier circuit after s.s rectification in a tube amplifier. I wondered if a particular mosfet can somehow change the overall sound, I swapped from 2SK1603 to a more powerful IRFP450 but I have an impression that the previous was better (more neat and detailed), so I'm a little bit confused
Transistor Capacitance Multiplier Circuit Design ...
https://www.electronics-notes.com/articles/analogue_circuits/transistor/capacitance-multiplier-circuit.php
The basic capacitance multiplier circuit is essentially a simple emitter follower with a capacitor on the base and a feed resistor from the input to the base to turn the transistor on. A capacitor from the base to ground provides the smoothing. Basic transistor capacitance multiplier. The capacitance multiplier circuit operation is quite straightforward.
