<p>The amplifier (PSi) has two phase-shift stages (7j) controllable between an input transistor (M61) and an output terminal (66) of the amplifier. The input transistor comprises a control terminal that is connected to an input terminal (62) of the amplifier. Each phase-shift stage comprises a gain element (72j) connected in series with a delay element between the output terminal and the input transistor, where the input transistor is a common-source metal oxide semiconductor transistor or common-emitter bipolar transistor.</p> |
