Abstract

A transimpedance amplifier, designed in a digital 120-nm CMOS technology, used as preamplifier for optical burst-mode receivers in passive optical networks is presented. A wide optical input power range of 27 dB can be handled with a variable transimpedance without stability problems by varying the open-loop gain by a factor of 115. Noise and stability analysis of the optical receiver are presented. Sensitivities of - 31.3 dBm at 622 Mb/s and - 28.6 dBm at 1.25 Gb/s with a bit error ratio of 10^-10 and a pseudorandom bit stream of 2³¹-1 are achieved with a power consumption of 88.5 mW.
