Abstract

High-performance and very compact 40 Gb/s driver amplifiers were realized in mature 0.15 μm depletion PHEMT technology. The 3-stage lumped differential drivers feature a large differential 40 Gb/s output swing of up to 7.5 V_pp, RMS jitter of less than 800 fs, rise and fall times of less than 10 ps and more than 27 dB gain. The small size (1.4×1.7 mm) and ability to have DC coupled in- and output, enable compact and cost-effective optical 40 Gb/s long-haul transmitters with system grade NRZ and RZ eye diagrams.
