摘要

我们提出了用InP/InGaAs HBTs制造的90 GHz工作的1/8数字分频IC，其电流增益截止频率(f/sub /spl tau//)超过150 GHz，最大振荡频率(f/sub max/)超过200 GHz。据我们所知，这个开关频率是有史以来最高的数字分频器报道。为了实现超快运算，采用了一种新颖的动态切换触发器(T-FF)。

90 GHz operation of a novel dynamic frequency divider using InP/InGaAs HBTs

We present 90 GHz operation of a 1/8 digital frequency divider IC fabricated with InP/InGaAs HBTs having a current gain cutoff frequency (f/sub /spl tau//) of over 150 GHz and a maximum oscillation frequency (f/sub max/) of over 200 GHz. To our knowledge, this toggle frequency is the highest ever reported for digital frequency dividers. A novel dynamic toggle flip-flop (T-FF) was employed in order to achieve ultrafast operation.
