Abstract

An amplifier circuit for actuating a light diode is provided. The amplifier circuit may have a small output impedance of approximately 3 Ohms, a large bandwidth having a lower threshold frequency of 200 kHz and an upper threshold frequency of 5 MHz, for example, and an amplitude of the output current of several 100 mA, for example. The amplifier circuit may have an entry stage for actuating a driver circuit that actuates the light diode by means of a direct current supply.
