From an input signal, and using an unusual current source, this circuit generates a ramp, that is, a voltage that grows linearly up to a certain value, and then falls.
We found this circuit in a 1972 documentation. The transistor, in fact, is a unijunction that can...
We found this circuit in Radio Electronics magazine from June 1960. The four-transistor circuit is...
This circuit was found in an old documentation. It converts DC voltages and its maximum current...
