METHOD FOR REGULATING VOLTAGE ACROSS DRAIN-SOURCE ELECTRODES OF OUTPUT-STAGE TRANSISTORS IN BROADBAND POWER AMPLIFIER AND OUTPUT STAGE IMPLEMENTING IT Russian patent published in 2005 - IPC

FIELD: broadband power amplifiers.

SUBSTANCE: proposed method for regulating output voltage across drain-source electrodes of output-stage transistors incorporated in broadband power amplifier operating in B mode using complementary transistors connected in common-drain circuit includes maintenance of stable voltage across transistor drain relative to its source that reduces impact of complex dynamic load, as well as connection of transistor drains in stage side through current supply on current-setting resistor thereby affording dispersion of drain-source capacity of first cut-off transistor through current-setting resistor by second-follower current.

EFFECT: reduced nonlinear distortions.
