Abstract: A radiofrequency harvester circuit may be used in a battery-less RFID device. The harvester circuit includes an antenna unit that captures radiofrequency signals and harvesting circuitry coupled to the antenna unit for collecting energy from the radiofrequency signals captured by the antenna unit. The antenna unit is selectively tunable at a plurality of tuning bands that are scanned by selectively tuning the antenna unit at different frequency bands and sensing respective values indicative of the power of radiofrequency signals captured by the antenna unit at the frequency bands scanned. A highest value out of said respective values for the power of radiofrequency signals as well as the frequency band in the plurality of tuning bands of the antenna unit providing the aforesaid highest value are identified and the harvester circuit is operated with the antenna unit tuned at the frequency band providing the highest value thus identified.

Abstract: A fully differential operational amplifier is provided. The amplifier has input nodes and includes a differential input stage for receiving input signals over the input nodes and providing output signals on first and second intermediary nodes. The amplifier includes a fully differential amplification stage having positive and negative inputs coupled to the first and second intermediary nodes, respectively. The amplifier includes a first compensation transistor having conduction terminals coupled to the first intermediary node and a first node, and a control terminal coupled to a negative output of the fully differential amplification stage. The amplifier includes a second compensation transistor having conduction terminals coupled to the second intermediary node and a second node, and a control terminal coupled to a positive output of the fully differential amplification stage. The amplifier includes positive and negative output stages for providing amplifier outputs and feeding the outputs back to the amplifier.
