摘要

在本文中，我们报告了两种使用AlGaAs/GaAs HBT实现的宽带放大器。一个是达林顿反馈放大器，另一个是跨阻放大器。在前一种电路中，实现了9.5 dB的直流增益和40 GHz的-3 dB带宽。在后一种电路中，实现了50 dB/spl ω /的跨阻增益和27 GHz的-3 dB带宽。据我们所知，它们是每个电路配置中速度最高的。

DC to 40 GHz broad-band amplifiers using AlGaAs/GaAs HBT's

In this paper, we report two types of broad-band amplifiers implemented with AlGaAs/GaAs HBT's. One is a Darlington feedback amplifier and the other is a transimpedance amplifier. In the former circuit, a DC gain of 9.5 dB and a -3 dB bandwidth of 40 GHz were achieved. In the latter circuit, a transimpedance gain of 50 dB/spl Omega/ and a -3 dB bandwidth of 27 GHz were achieved. To our best knowledge, they are the highest speed in each circuit configuration.
