Patent attributes
Shared-current electronic systems (120, 130, 140, 150, 160, 170, 180, 190, 200, 210, and 220) include two or more electronic devices, such as an electronic device (Q1), a baseband processor (110), and a multiplier/up-converter (112), that are connected in dc series or dc series-parallel, that may be connected in rf series, and that either fixedly or variably share portions 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 (122, 162, 162A, and/or 162B) for precisely proportioning the regulated dc source voltage to one or more of the dc series-connected electronic devices irrespective of production variations in operating parameters of the electronic devices and/or drift of the electronic devices.
