Design of an Optical Receiver using Transimpedance amplifier with light detector and Equalization in MOS Technologies

— In circuits and systems for short distance communications optical receivers with monolithically integrated photo detectors can be used. In this the entire optical receiver can be implemented in standard CMOS technology. Not only save the extra overhead and cost during assembly for multichip solutions, but also ground bounce issues, ESD problems, and parasitic associated with bond pads and bond wires can also be eliminated.CMOS technology uses a combination of spatially modulated light (SML) detector, Transimpedance amplifier, differential gain stage, Post amplifier and an analog equalizer while designing a optical receiver. A transimpedance amplifier is operated with 3.3v supply, while the rest of the circuit blocks are powered with 1.8v supply.These different circuits are implemented using a TOP Spice tool and PSpice tool and compared the results
