Abstract: A photovoltaic power generation plant includes a plurality of photovoltaic generators cooperative in producing photovoltaic power. Coupled with the photovoltaic generators in the plurality of photovoltaic generators are respective sensor devices, the sensor devices including sensor circuits of the individual current-to-voltage characteristics of the photovoltaic generators. The sensor circuits in the sensor devices can be activated to sense the individual current-to-voltage characteristics of the photovoltaic generators, with the individual current-to-voltage characteristic being indicative of the functionality of each photovoltaic generator.

Abstract: A embodiment method, for linearizing a transmission signal resulting from a quadrature amplitude modulation of an analog baseband signal and a radiofrequency amplification, comprises a demodulation of a feedback signal taken from the transmission signal, a comparison between the demodulated feedback signal and the baseband signal, a digital calculation of a predistortion control signal based on the comparison, and an analog predistortion of the analog baseband signal controlled by the predistortion control signal.

Abstract: A push-pull amplifier includes a pair of active devices driving the primary side of a double distributed active transformer (DDAT). The primary side of the DDAT includes a cascaded arrangement of primary windings of a first set of transformers with the active devices coupled ends of cascaded arrangement of primary windings. The secondary side of the DDAT includes a cascaded arrangement of secondary windings of a second set of transformers coupled to a load. Secondary windings of the first set of transformers drive inputs of respective active stages. Outputs of the active stages drive respective primary windings of the second set of transformers.

Abstract: An oscillator has an oscillator output emitting an oscillating signal. The oscillator includes oscillator cores which each have a same circuit topology. A set of configuration switches couple a selected number of oscillator cores in parallel to generate the oscillating signal. The oscillator cores are arranged with a symmetry around a central axis. The planar inductors of the oscillator cores are arranged in a petal-like pattern with the planar inductors forming the petals of the petal-like pattern. The selected coupling of the oscillator cores in made in response to a selected phase noise threshold of a modulation device which receives the oscillating signal.
