Abstract

A 5Gb/s cross coupled transimpedance amplifier (TIA) & limiting amp(LA), regulated cascode(RGC) is realized in a 0.18$\mu$m CMOS technology for optical printed circuit board applications. The optical receiver demonstrates $92.8db{\Omega}$ transimpedance and limiting amplifier gain, 5Gb/s bandwidth for 0.5pF photodiode capacitance, and 9.74mW power dissipation from 1.8V, 2.4V supply. Input stage impedance is $50{\Omega}$. The circuit was implemented on an optical PCB, and the 5Gb/s data output signal was measured with a good data eye opening.

5Gb/s대역 크로스커플 구조의 트랜스임피던스 증폭기 및 제한증폭기가 연결된 광 수신기를 광 PCB에 응용하기 위해 설계 하였다. 회로는 0.18um CMOS 공정으로 구현되었다. 광 수신기는 0.5pF 광 다이오드 기생 캐퍼시턴스에서 $92.8db{\Omega}$ 임피던스 이득과 5Gbps의 주파수 대역을 갖는다. 그리고 1.8V, 2.4V 공급전압에서 9.74mV의 전력소모를 보인다. 입력단의 임피던스는 $50{\Omega}$ 이다. 회로를 광 PCB기판에 올려 광신호 송신 실험하여 5Gb/s 데이터의 수신을 확인하였다.
