Abstract :
The bandwidth of the photodiode in an optoelectronic integrated circuit with a single 5 V supply is extended from 20MHz to 771MHz by an innovative on-chip voltage-up-converter. A shunt-regulator keeps the die are small and exploits breakdown voltages of available devices best. Rise and fall times below 0.5ns are achieved allowing operation at data rates in excess of 1Gbits/s. A possible receiver sensitivity of -22.5 dBm is obtained for a wavelength of 670nm.
