ABSTRACT:
The optoelectronic device includes a photo diode and an amplifier, which amplifies output of the photo diode. The amplifier includes an input stage and an output stage. In one embodiment, the input stage has a series connection to a resistor, which is connected to a ground. The output stage has a connection to ground that does not overlap the series connection. In another embodiment, the input stage has a first connection to a bypass capacitor, which is connected to a power source. The output stage has a separate, second connection to the capacitor, which prevents high frequencies from flowing between the input stage and said output stage via a connection to the power source.
