Abstract :
The body contact in a Si photodiode fabricated by standard CMOS technology is used to eliminate the slow diffusion photogenerated carriers to enhance the response. The proposed photodiode demonstrates significant reduction in the long tail from pulse measurement and consequently shows the electrical bandwidth of 2.8 GHz and 5 Gbit/s eye diagram.
