Abstract
This paper presents a high-speed, l ow-power modu-
lator driver featuring a novel modi fied breakdown voltage doubler
(BVD) topology. Further speed enhancement and reduction of
power consumption is achieved by multi ple frequency compen-
sation methods. An optimization method combining small and
large-signal analyses is presen ted. The driver was fabricated in
a 0.25-
m SiGe BiCMOS technology with of up to 180 GHz.
It features 13-dB differential gain, a small-signal bandwidth of
33.7 GHz and deli
