Varactors are diodes optimized to take advantage of this effect. The varactor parametric amplifier, then, has two inputs: the incoming signal and a locally-generated signal that varies the ...

You need a TVS diode because many voltage regulators do not have the ability to sink current, nor can they respond fast ...

Using a few simple formulas you can then calculate how much noise the amplifier produced ... to go for the classic method of using a vacuum diode. He describes the design and analysis of a ...

Design engineers aiming to protect the input and output of op amps have several options. They can use an electrostatic ...
