“…Although it is known that the folded-cascode OTA exhibits somewhat better settling time [19] and lower input referred noise [18, pp. 276], the current mirroring topology was chosen here due to its excellent large-signal response [20]. To ensure low-noise operation, the transconductance of the mirroring transistors was chosen sufficiently small, thus trading noise performance for signal swing.…”

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.

“…Due to the Miller-effect, this capacitance forms a low-frequency pole with the gate resistance of M l' resulting in an additional phase shift that degrades the amplifier stability. This problem is eliminated in the "Current Gain amplifier" [5] of Fig. 1.7.b.…”

SUMMARYA new CMOS current mirror is presented which has the static characteristic of the cascode current mirror and a highfrequency performance equivalent to or better than that of the simple current mirror. Moreover, the circuit proposed does not present the instability problem of the improved cascode utilized to increase the high-frequency response.The circuit is designed using CMOS 2 +m technology with various aspect ratios and simulated with the SPICE programme.
