Shared-current electronic systems with precise proportioning

Abstract

Shared-current electronic systems (, and) include two or more solid-state electronic devices, such as a solid-state amplifying device (Q), a baseband processor (), and a multiplier/up-converter (), that are connected in dc series or dc series-parallel, that may be connected in rf series, and that either fixedly or variably share percentages of a dc source voltage. Various embodiments produce separate rf outputs, variably shift the phase of a single rf output, variably shift rf power between/among rf outputs, or produce a frequency-compressed modulation. The apparatus includes means (A, and /orB) for precisely proportioning percentages of the regulated dc source voltage to the dc series-connected electronic devices irrespective of production variations in operating parameters of the electronic devices and/or drift of the electronic devices.
