Abstract:
An optical interconnection receiving module comprising:a plurality of photodiodes, each of which receives an optical signal on a channel and converts the optical signal into an electrical signal; at least one power pad; a power supply line coupled to said at least one power pad; and a plurality of sets, each set comprising: a first amplifier for amplifying the electrical signal converted by one of said photodiodes; a determining circuit for determining the signal amplified by said first amplifier based on a reference voltage; a reference voltage generating circuit for generating the reference voltage, and a capacitance device formed between said reference voltage generating circuit and said at least one power pad; wherein each of said plurality of sets of said first amplifier, said determining circuit, said reference voltage generating circuit and said capacitance device a reformed on a single semiconductor chip along with said power supply line and said at least one power pad; and wherein each of said first amplifier and said reference voltage generating circuit are electrically connected to said at least one power pad through said power supply line.
