摘要：The input of a voltage-controlled constant-current source is connected, apartfrom via the RC network with a resistor in the series branch and a capacitor in the shuntbranch, to a first terminal, also via a further resistor and a diode to a second terminal. Areference voltage supplied to the input via the first terminal and the RC network resistorcan be suppressed by a control voltage supplied via the second terminal, the diode andthe further resistor. The control voltage suppresses the reference voltage due to theresistance ratios. The junction between the further resistor and the diode is connected via
a third resistor to the output of the constant-voltage source via which, when the diode isloaded in the reverse direction, a reverse current flowing through it is bypassed whicheliminates the possibility of the reverse current influencing the constant-voltage source.
