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 Vpp, 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.
