Improved bandwidth for large photodiode receiver in lifi systems

A wireless receiver for optical communication, the wireless receiver comprising:

• a first photodiode;
• a first semiconductor switching element comprising a first connection and a second connection, wherein the first connection of the first semiconductor switching element is coupled to an output of the first photodiode;
• a second photodiode;
• a second semiconductor switching element comprising a first connection and a second connection, wherein the first connection of the second semiconductor switching element is coupled to an output of the second photodiode;
• a transimpedance amplifier, TIA, comprising a first input, wherein the second connection of the first semiconductor switching element and the second connection of the second semiconductor switching element are coupled to the first input of the TIA,
• wherein the TIA further comprises a third semiconductor switching element and an operational amplifier, wherein the third semiconductor is coupled between the first input of the TIA and an input of the operational amplifier and wherein a second input of the TIA is coupled to a second input of the operational amplifier.
