Despite the monolithic op amp being older than SPICE simulators, comprehensive op-amp SPICE modeling left a lot to be desired ...

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 ...

Learn how microphones and amplifiers work together to convert sound to electrical signals for clear audio output.

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 ...
