Found in an ancient American documentation, this circuit can generate signals up to 40 MHz for a Z80, microcontroller widely used at the time. The circuit must be powered with 5 V and also serves as a shield.
Depending on the components, given in the table, this circuit can amplify signals of 100 MHz or...
This circuit was found in a 1967 EEE. The components are from that time, but the circuit can be...
The CMOS oscillator illustrated in the figure has a frequency that depends on the temperature...
