摘要
Abstract
As the rapid growth of the signal bandwidth in aerospace data communications,the data rate of laser diode driver(LDD)in aerospace optical fiber communication has enter the era of hundred-gigabits.For the sake of radiation harden and high reliability design,the introduction of extra parasitic factor requires more efforts in the circuit design to compensate the loss of bandwidth at high frequency.This work proposes an adaptive continue time linear equalizer(CTLE)which is based on a SiGe BiCMOS platform giving a programma-ble loss compensating capability up to 16 dB at 14 GHz.It has the capable of adaptive gain compensation adjustment,supporting up to 25 Gb/s NRZ signal transmission.关键词
