A 2.4GHz-bandwidth OEIC with voltage-up-converter [optical receiver]

Abstract

This work describes a realisation of an optoelectronic integrated circuit (OEIC) with an integrated voltage-up-converter (VUC) to enhance the frequency response of an integrated pin photodiode. The VUC produces a voltage of 11 V and improves the bandwidth of the OEIC from 1.5 GHz to 2.4 GHz for a single 5 V supply without any additional external components. For a maximum measured data rate of 3 Gbps and a bit error rate of 10/sup -9/ a sensitivity of -24.3 dBm at a wavelength of 660 nm is obtained. The OEIC is implemented in a modified 0.6 /spl mu/m silicon BiCMOS technology with f/sub T/=25 GHz.
