摘要

我们已经建立了一个宽带双极跨阻前置放大器，其有效跨阻增益为39 dB ω， 1.5 dB/sub p-p/纹波。采用f/sub T/为120 GHz、f/sub max/为59 GHz的InP/InGaAs复合集电极异质结双极晶体管(HBTs)，实现了28 GHz的电路带宽。电路紧凑，尺寸为975*675 μ m/sup 2/。在2.7 v的单电源电压下，功耗仅为48.6 mW。

A 28 GHz transimpedance preamplifier with inductive bandwidth enhancement

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.<>
