This circuit is from Motorola's Linear Databook from 1990. The integrated circuit and transistors are uncommon, but the circuit can be assembled with equivalents.
We found this circuit in a component manual from the 80s. R1 has values between 1k and 10k. R1 has...
In the figure we have an oscillator for microcontrollers capable of operating in the frequencies of 10,...
This oscillator produces a modulated signal using a unijunction transistor. We found it in an...
