TRAVELING WAVE AMPLIFIER WITH SUPPRESSED JITTER |
摘要 |
A traveling wave amplifier (TWA) with suppressed jitter is disclosed. The TWA includes a plurality of unit amplifiers with the differential arrangement comprised of a pair of transistors and a cascade transistors connected in series to the switching transistors. The unit amplifiers further includes current sources to provide idle currents to the cascade transistors. Even when the switching transistors fully turn off, the idle currents are provided to the cascade transistors, which set the operating point of the cascade transistor in a region where an increase of the base-emitter resistance is suppressed.
