burst-mode passive optical network(PON) transimpedance preamplifier regulated cascade(RGC) peak detector auto-gain-control threshold extraction
A 10 Gbit/s burst-mode preamplifier is designed for passive optical networks(PONs). To achieve a high dynamic range and fast response, the circuit is DC coupled, and a feed-back type peak detector is designed to perform auto-gain-control and threshold extraction. Regulated cascade(RGC)architecture is exploited as the input stage to reduce the input impedance of the circuit and isolate the large parasitic capacitance including the photodiode capacitance from the determination pole, thus increasing the bandwidth. This preamplifier is implemented using the low-cost 0.13 μm CMOS technology. The die area is 425 μm×475 μm and the total power dissipation is 23.4 mW. The test results indicate that the preamplifier can work at a speed from 1.25 to 10.312 5 Gbit/s, providing a high transimpedance gain of 64.0 dBΩ and a low gain of 54.6 dBΩ with a dynamic input range of over 22.9 dB. The equivalent input noise current is 23.4 pA/Hz1/2. The proposed burst amplifier satisfies related specifications defined in 10G-EPON and XG-PON standards.
