Abstract :
We have built a broadband bipolar transimpedance preamplifier exhibiting an effective transimpedance gain of 39 dB Omega with 1.5 dB/sub p-p/ ripple. Using InP/InGaAs composite collector heterojunction bipolar transistors (HBTs) with an f/sub T/ of 120 GHz and f/sub max/ equal to 59 GHz, a 28 GHz circuit bandwidth was demonstrated. The circuit is compact measuring 975*675 mu m/sup 2/. A low power dissipation of only 48.6 mW was achieved for a single supply voltage of 2.7 V.<>
