“…Several BMRx designs employ digital-to-analog (D/A) converters to compensate various dc offsets [2], [3], [10]. Obviously, it is important to know the required resolution of such D/A converters, as increased resolution drastically increases circuit complexity and required die area.…”

“…Thus, it is clear that the fast extraction of the decision threshold results in unavoidable dc offsets. Therefore, many dc-coupled BMRxs include extensive circuitry to remove or compensate these dc offsets [2], [4], [10]. In order to properly dimension such dc offset compensation circuitry, it must be thoroughly understood how random dc offsets degrade optical receiver sensitivity.…”

Abstract-This paper presents the influence of random direct current (dc) offsets on the sensitivity of dc-coupled burst-mode receivers (BMRxs). It is well known that a BMRx exhibits a noisy decision threshold, resulting in a sensitivity penalty. If the BMRx is dc coupled, an additional penalty is incurred by random dc offsets. This penalty can only be determined for a statistically significant number of fabricated BMRx samples. Using Monte Carlo (MC) simulations and a detailed BMRx model, the relationship between the variance of this random dc offset, the resulting sensitivity penalty, and BMRx yield (the fraction of fabricated BMRx samples that meets a given sensitivity specification) is evaluated as a function of various receiver parameters. The obtained curves can be used to trade off BMRx die area against sensitivity for a given yield. It is demonstrated that a thorough understanding of the relationship between BMRx sensitivity, BMRx yield, and the variance of the random dc offsets is needed to optimize a dccoupled BMRx with respect to sensitivity and die area for a given yield. It is shown that compensation of dc offsets with a resolution of 8 bits results in a sensitivity penalty of 1 dB for a wide range of random dc offsets.Index Terms-Avalanche photodiodes, bit error rate (BER), burst-mode receiver (BMRx), optical access network, optical receiver.

Abstract-This paper presents a 1.25-Gb/s burst-mode receiver (BMRx) for upstream transmission over gigabit passive optical networks (G-PONs). The dc-coupled receiver uses a unique arrangement of three limiting amplifiers to convert the bursty input signal to a current mode logic output signal while rejecting the dc offset from a preceding transimpedance amplifier. Peak detectors extract a decision threshold from a sequence of 12 successive nonreturn-tozero (NRZ) 1's and 12 successive NRZ 0's received at the beginning of each packet. Automatic compensation of the remaining offsets of the BMRx is performed digitally via digital-to-analog converters. The chip was designed in a 0.35-m SiGe BiCMOS process. The receiver contains an APD with a gain of 6 and a transimpedance amplifier and shows a sensitivity of 32.8 dBm and a dynamic range of 23.8 dB. A sensitivity penalty of 2.2 dB is incurred when a packet with average optical power of 9 dBm precedes the packet under consideration, the guard time between the packets being 25.6 ns. The BMRx includes activity detection circuitry, capable of quickly detecting average optical levels as low as 35.5 dBm. The performed measurements prove that the receiver meets the G-PON physical media dependent layer specification defined in ITU-T Recommendation G.984.2.

“…Nowadays, the challenge arises from the time response of optical amplifier with micro second bursts of data at the upstream SuperPON is consider solved by installing burst mode receiver at the optical line termination unit (OLT) [2]. Unfortunately, the accumulation of ASE noise at the upstream of SuperPON still needs attentions.…”
