<p>The semiconductor photo component (2) has its first output signal terminal connected to an input of an amplifier (8) and its second output terminal is connected via a capacitor (9) to the amplifier output (6) the amplifier transfer factor between input and output is positive, greater than zero and smaller than 1 + Ce/Cd, where Ce is the resultant capacitance between the first output terminal and reference potential, and Cd the photo component capacitance between the two terminals. The amplifier (8) has two inputs, and the second input is connected to earth. The terminal of the photo component (2) connected to the amplifier (8) is connected to earth via a resistor (4) and a capacitor (7) in parallel.</p> |
