—This paper deals with the challenges in the design of millimeter-wave CMOS radios and describes circuit and architecture techniques that lead to compact, low-power transceivers. Candidate topologies for building blocks such as low-noise amplifiers, mixers, oscillators, and frequency dividers are presented. Also, a number of radio architectures that relax(More)
The 2009 pandemic H1N1 influenza pandemic demonstrated the global health threat of reassortant influenza strains. Herein, we report a detailed analysis of plasmablast and monoclonal antibody responses induced by pandemic H1N1 infection in humans. Unlike antibodies elicited by annual influenza vaccinations, most neutralizing antibodies induced by pandemic(More)
—Fundamental oscillators prove the existence of gain at high frequencies, revealing the speed limitations of other circuits in a given technology. This paper presents an oscillator topology that employs feedback from an output stage to the core, thus achieving a high speed. The behavior of the proposed oscillator is formulated and simulations are used to(More)
—A critical issue in the design of high-speed ADCs relates to the errors that result from comparator metastability. Studied for flash architectures in the past, this phenomenon assumes new dimensions in pipelined converters, creating far more complex error mechanisms. This paper presents a comprehensive analysis of comparator metastability effects in(More)
A pipelined ADC digitally calibrates capacitor mismatches in its 4-bit first stage and the gain error in the first 5 stages. Using a one-stage op amp with a gain of 10 and realized in 65-nm CMOS technology, the ADC digitizes a 490-MHz input with an SNDR of 52.4 dB, achieving an FOM of 0.097pJ/conversion-step. This paper describes a pipelined ADC(More)
