—The advent of wideband systems, e.g., software defined radios, cognitive radios and UWB technology, motivates research for new transceiver architectures and circuit topologies to arrive at compact and low power solutions. Reference frequency generation in wideband CMOS receivers is usually power and area hungry. In this paper a wide band quadrature(More)
—Scaled CMOS proves to be suitable for the design of transceiver ICs at micro-and millimeter-waves. The effort is presently toward compact and low-power solutions in view of integrating several transceivers on the same chip enabling phased array systems. In this paper we present a 24 GHz receiver, based on a subharmonic direct conversion architecture,(More)
Receiver ICs realized in CMOS technology leverage the narrowband nature of wireless standards to meet specifications at low power levels. The advent of wideband systems, e.g. software-defined radios and UWB technology, is determining new emphasis on innovative techniques for key RF circuit blocks, and on synthesizers in particular [1-4].(More)
We developed a method for the reconstruction of a 100 kb DNA fragment into a bacterial artificial chromosome (BAC). The procedure makes use of iterative rounds of homologous recombination in Escherichia coli. Smaller, overlapping fragments of cloned DNA, such as cosmid clones, are required. They are transferred first into a temperature-sensitive replicon(More)
— Direct conversion to DC by means of quadrature SubHarmonic mixers is a promising solution to arrive at low power silicon receivers working at millimeter waves. A lower frequency local oscillator (LO) does not compromise receiver performances while takes advantage of the higher quality of tuning elements and avoids high frequency, power-hungry dividers in(More)
