Traveling wave amplifier with pre-emphasis function |
摘要 |
A traveling wave amplifier (TWA) primarily for driving a semiconductor optical device is disclosed. The TWA of an embodiment provides a plurality of differential amplifiers of the first type and an additional differential amplifier of the second type, where are they are connected between the input and the output of the TWA. The differential amplifiers of the first type provide a first delay from the input to the output, while, the differential amplifier of the second type provide a second delay longer than the first delay between the input and the output of the TWA. |
