【 摘 要 】

References(8)Cited-By(2)Using 1-µm InP HBT technology, a transimpedance amplifier (TIA) IC for optical links using 100-Gb/s dual polarization quadrature phase shift keying (100-G DP-QPSK) was designed and fabricated. Its wide dynamic range of 0.2∼2mAppd input current and good linearity of less than 3.3-% total harmonic distortion (THD) were confirmed. Also, externally controllable functions such as output amplitude adjustment, output shutdown, and auto/manual gain control switching were successfully implemented with InP HBT technology.
