  • SiGe differential cascode amplifier with miller effect resonator
    Patent number: 7205836
    Abstract: A high-power, high frequency (1–100 GHz) power amplifier, made using SiGe transistors. A differential common-emitter amplifier section supplies the voltage amplification, allowing the total voltage swing of the amplifier to be twice the breakdown voltage of the individual transistors. Current amplification is supplied by a differential common-emitter amplifier section, connected in cascode with the differential common-emitter amplifier section. Appropriately chosen resonators in the cascode connection resonate out the Miller effect, negative current feed back of the circuit at the amplifier's operational frequency, allowing the amplifier to provide high power output at the operational frequency.
