Abstract:A high-linearity and temperature-insensitive 2,4 GHz power amplifier (PA) with dynamic-bias control is realized in a SiGe HBT technology with 0.9 pm emitter width. Due to the bias linearization, the PldB of 27 dBm is only 0.5 dB smaller than PSsr, which i s the record low to the best of our knowledge. With simple temperature-insensitive bias, the total current deviations from the room temperature are smaller than 6% and 10% at the linear Pa,, (24/20 dBm) for 802.1Ib and 802.11g, respectively at the test temper… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
