Abstract
A discriminator circuit is arranged to emit a defined output signal when a certain value of a variable direct supply voltage is reached. The discriminator circuit comprises a current mirror circuit in the form of a first transistor connected to the supply voltage source and arranged to divide an input current into two current branches by means of two collector electrodes. One current branch comprises a Zener diode and a first resistor and this branch is connected to a limiter circuit for limiting the rise in the supply voltage to a predetermined maximum value and the other current branch comprises a second resistor and a second transistor for emitting an output signal from the discriminator circuit.
