Claim:
1. A method for implementing enhanced CMOS inverter based optical Transimpedance Amplifiers (TIAs) comprising: providing a transimpedence amplifer (TIA) including a photo-detector, and the TIA being formed by a first TIA inverter and a second TIA inverter; providing the first TIA inverter with an input from a cathode side of the photo-detector and the second TIA inverter with an input from an anode side of the photo-detector; providing a replica TIA being formed by two replica inverters, said two replica inverters coupled to a respective input of a first operational amplifier and a second operational amplifier; and providing said first operational amplifier and said second operational amplifier in a feedback configuration for respectively biasing a set voltage level at the cathode side of the photo-detector input of said first TIA inverter and at the anode side of the photo-detector input of said second TIA inverter.
