Abstract
An amplification device relating to the field of the amplification of ultra-wideband electrical signals from the dc to the microwave range, and more precisely from dc to microwaves of over 6 GHz, notably for the amplification of signals transmitted at very high bit rates on optic fibers, of the type including at least one ampification stage, the active amplification element of which is a field-effect transistor mounted as a common source, each of the amplification stages including means for the simultaneous maintaining of a positive dc voltage bias on the drain of the amplification transistor and a negative or zero dc bias on the gate of the transistor. This device may advantageously be made in monolithic integrated circuit form.
