The circuit is a very simple one using a dual-gate FET, ... which when characterised was found to have a 1.3 GHz bandwidth and a very low input capacitance.

I once had the same need to measure some stuff with a low capacitance probe. Been on the cheap I went to the big auction web page and found a “RF Active Probe 0.1 – 1500 MHz – 1.5 GHz ...

Figure 2: Working principle of a negative-capacitance field-effect transistor (NC-FET) with a ferroelectric material as an insulator, ...

Yorba Linda, CA. Today Cal Test Electronics introduced a new active FET probe kit. The CT4121 is a compact FET probe with high input resistance and low input capacitance. With a 1.2-GHz bandwidth ...

In principal, the ICs implement a capacitance multiplier circuit to emulate the Y-capacitors in a conventional passive filter design. They do while sitting amongst smaller filter inductors and ...

The MVDR high-voltage inductive capacitor is specifically designed for use with CRT displays and video monitors. It also functions for high-voltage power supplies and multiplier circuits. The ...
