The effect can be very pronounced. For example, a chart in the video shows that if you had an amplifier with gain of -60 based around a tube, a 10 kΩ input impedance could support 2.5 MHz, in theory.

This report discusses the design of circuits using variable-capacitance diodes as high efficiency frequency multipliers with particular reference to their use at v.h.f. and u.h.f. Two multipliers ...

Current conveyors and capacitance multipliers are fundamental building blocks in modern CMOS technology, facilitating advanced analog signal processing and integrated circuit design.
