Equivalent operational amplifiers can be used on this crystal-controlled oscillator. The circuit is from old documentation and can be changed to operate on other frequencies.
The circuit is from Motorola's Linear Databook from 1990, but the configuration is current because...
In the figure we have the simplest way to implement a power supply for a tunnel diode. The...
This circuit was found in documentation from the 1980s. The circuit can be implemented with other...
