Abstract—The advent of wideband systems, e.g., software de-
fined radios, cognitive radios and UWB technology, motivates re-
search 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 demodulator, based
on m
