Comparison of CMOS and BiCMOS optical receiver SoCs

Highly sensitive optical receivers in BiCMOS, sub-micron and deep-sub-micron CMOS technology are compared. Special attention is paid to burst-mode receivers with a wide-dynamic input range and with fast gain switching. A new burst-mode receiver design in 0.12 µm CMOS technology for a data rate of 2.5 Gb/s and very fast gain switching is presented. Handling a wide dynamic range leads to stability problems when the transimpedance gain of the preamplifier is decreased. These stability problems could be solved by decreasing the open-loop gain of the transimpedance amplifier. Stability analysis of this solution is presented here.

“…Another folded-cascode TIA was presented in [8] in a 0.18 µm CMOS technology. The measured sensitivities were −30.7 dBm and −23.7 dBm with a BER of 10 −10 and a PRBS of 2 31 −1.…”

SUMMARYThis work shows that the performance of optical receivers designed in silicon deep-sub-micron CMOS technologies competes successfully with more expensive SiGe-BiCMOS receivers in data rate and sensitivity. In burst-mode applications of passive optical networks, the transimpedance of the low-noise amplifier has to be switched very fast requiring, the exclusion of oscillations. To meet the burst-mode requirements, our design for 2.5 G bit/s in 120 nm CMOS offers a fast switching of the transimpedance within 3 ns and proves a low-distortion signal detection.
