However, it is a good analog of how a parametric amplifier works. In a real circuit, the parameter often is capacitance — although it doesn’t have to be — but instead of using a mechanically ...

Any method of periodically varying the capacitance may be used, or alternatively the inductance may be varied. Moreover, such a circuit can be used as an amplifier, since, at the fundamental ...

Series 5820 Charge Amplifiers offer dual signal outputs, one is biased about +2.50 VDC and one unbiased capacitance and the other one is unbiased capacitance coupled. They come in seven standard ...
