The system design of an integrated microwave imaging radar for the diagnostic screening of breasts cancer is presented. A custom integrated circuit implemented in a 65-nm CMOS technology and a pair of patch antennas realized on a planar laminate are proposed as the basic module of the imaging antenna array. The radar operates on the broad frequency range(More)
Nanotechnology is a multidisciplinary field originating from the interaction of several different disciplines, such as engineering, physics, biology and chemistry. New materials and devices effectively interact with the body at molecular level, yielding a brand new range of highly selective and targeted applications designed to maximize the therapeutic(More)
—A 65-nm CMOS receiver tailored for breast cancer diagnostic imaging is demonstrated for the first time. The receiver shows 31-dB conversion gain, NF dB, 28 dBm, IIP dBm and IIP dBm over a band from 1.75 to 15 GHz. A programmable injection-locked divider generates quadrature LO signals with a I/Q phase error over three octaves without requiring any(More)
Wide-band receivers at mm-waves enable several Gbit/s communications with simple modulation. This work presents the design of an ultra wide-band LNA in 28nm CMOS. Common source stages are stacked in a current-sharing configuration and coupled through third-order L-C band-pass networks. In addition, the stages are stagger-tuned to maximize bandwidth and gain(More)
Generation of broadband power at mm-wave frequencies with high efficiency is challenging, because of the low gain of CMOS devices and the trade-off between efficiency and gain-bandwidth product (GBW). Power amplifiers (PAs) with multiple paths, leveraging power splitters and combiners are the most popular choice to achieve high output power, but tradeoff(More)
