This circuit converts a constant input current intensity into a voltage given by Vo = -R x I. T1 must be equal to R. The operational admits equivalent.
I found this circuit in a documentation about thyristors from the 70s. The circuit uses a diac...
This circuit triggers by choosing the higher of two voltages. The circuit is from a 1964...
The integrated circuit used in this 80's mixer is the LM301A. However the circuit can be used to...
