High-gain SiGe transimpedance amplifier array for a 12×10 Gb/s parallel optical-fiber link

Design for Stability of High-Speed Integrated Photoreceivers: A Tutorial

“…The interface between the device under test and the test equipment has to be adequately considered for valid measurements results. In this work, the test setup was inspired by the work from Rein Hans-Martins' team over the past decade [5,9,13,16,17] and particularly the paper form Jens Mullrich et al [16].…”

“…Although transimpedance amplifiers with differential outputs have been reported in the literature [13][14][15][16][17][18][19][20], single-ended to differential conversion stages are still streaky to implement. In fact, most designs will present some impairments namely: the two output signals are not perfectly symmetrical, the common mode voltage is different for the two outputs causing non-symmetric crossing points susceptible to generate more jitter, thus degrading the bit error rate (BER) and the signal integrity.…”

“…Although circuit performance at 10-Gb/s and higher has already been demonstrated for more than a decade [5][6][7][8][9][10][11][12][13][14][15][16][17][18], high-speed design techniques are still investigated to improve system's performance. In fact in 1990, Hans-Martin Rein [5] has provided a good review of circuit architectures suitable for high-speed communication systems.…”

“…To improve gain and noise performance, a more robust approach is to use a differential structure in order to take advantage of the common mode noise rejection property inherent to differential circuits. TIAs with differential outputs have been reported in the literature [12][13][14][15][16][17][18][19][20].…”

“…Although an important design effort is being carried out around the data rate of 10-Gb/s and higher [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], new design techniques are still in great demand to accurately address high-speed circuit design and stability. Actually, the majority of gigabit TIA designs have so far focused on the design-tradeoffs of the TIA such as transimpedance gain, bandwidth, noise, dynamic range, power dissipation, etc.…”
