A high sensitivity 10 Gb/s DCFL limiting amplifier with 0.2 μmGaAs MESFETs

摘要

This paper describes the successful operation of limitingamplifier IC by using the digital circuit of Direct Coupled FET Logic (DCFL). To achieve a high sensitivity and wide dynamic range, thelimiting amplifier configuration is newly demonstrated. The evaluationresults are the sensitivity of 10 mVpp, the wide dynamic range of 40 dBat 10 Gb/s, and 210 mW power dissipation
