- Abstract
- The sensitivity of an OEIC receiver depends essentially
on the physical sources of device and circuit noise referred
to its input, provided that the inter-symbol interference (ISI)
makes no significant contribution. For well designed receivers,
the latter situation can be realized only at an optimum bandwidth
(f3 dB-opt) for a given bit rate (B) or vice versa. In this paper,
we have determined the relationship between the bit rate and
the 3-dB bandwidth for negligible and pre-set levels of ISI for
an optimized p-i-n/HBT transimpedance receiver with adjustable
bandwidth.We have used the SPICE simulations in the frequency
domain to determine the effect of device and circuit noise, and
the SPICE transient analysis to determine the effect of ISI on the
sensitivity. The ratio f3 dB-opt=B has been found to vary from
0.65 to 0.45 when B changes from 10 to 20 Gbps for the OEIC
receiver used.
