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 Ferranti's 1974 transistor manual. Transistors are general-purpose types...
This circuit was found in a Dutch documentation from 1970. The circuit makes use of semiconductors that...
