The operational amplifier used in this circuit is uncommon nowadays. We obtained this circuit from documentation from the 1980s, but it can be adapted to use more modern equivalents.
Bipolar transistors are types of general use like BC548, while the power MOSFET can be of any type...
This circuit generates a signal rich in harmonics that extends up to close to 1 GHz, serving for...
This second-order low-pass Salen-Key filter was obtained from an American 1980s documentation. Formulas...
