This RCA / GE circuit from the 90s can be applied to any modern operational amplifier. The number of entries (installments) can be changed depending on the application.
This circuit is from the 1974 Motorola Unijunction Trigger Circuits for Gated Thyristor. The triac...
Found in old American documentation, this circuit can divide the frequency of a signal by 2 or 3...
This transceiver is also low power, but this time, it can generate signals in the 144 MHz band. In the...
