LOW-STRESS CASCODE STRUCTURE

摘要

An amplifier system comprises a cascode common-source (CS) amplifier including a plurality of transistors connected in a common-source configuration. A stress reducing circuit is connected to at least one of the plurality of transistors to equalize a voltage drop across the plurality of transistors. The stress reducing circuit includes a first transistor including a control terminal, a first terminal and a second terminal. The second terminal of the first transistor is connected to a first terminal of a first one of the plurality of transistors. A capacitance has a first terminal connected to the control terminal of the first transistor and a second terminal connected to a control terminal of a second one of the plurality of transistors.
