Good Future Background in the area

• Test Setup on visible light communication (VLC)

• Data Rate = 10Mbit/sec
• Distance = 150cm
• Increasing LED bandwidth by pole cancelling

Variable Bandwidth TIA and Limiting Amplifier for Maximum Sensitivity in Free Space Optical Links

• This receiver consists of a pre-current amplifier, TIA, BW control unit, offset cancellation and a limiting amplifier.
• The receiver is designed for the data rates of 16Mbps to 1Gbps between the distances of 100m to 1km.
• A total transimpedance gain and input referred noise of 117dB and 5.2pA/√?? was obtained. The total power consumption is 113mW.
• High sensitivity and the ability to steer the bandwidth to compensate for the channel variations loss
• A novel idea for a new clock data recovery architecture was proposed which can lock to the data while smoothly doubling the data rate without losing any of the information.
