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<8.6 dB, P1dB >-28 dBm, IIP3>-12 dBm and IIP2>22 dBm over a band from 1.75 to 15GHz. A programmable injection-locked divider generates quadrature LO signals with a I/Q phase error <1.5 over 3 octaves without requiring any calibration or tuning. The receiver shows a flicker noise corner as low as 40Hz, achieving a dynamic range of 106 dB.

Abstract
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<8.6 dB, P1dB >-28 dBm, IIP3>-12 dBm and IIP2>22 dBm over a band from 1.75 to 15GHz. A programmable injection-locked divider generates quadrature LO signals with a I/Q phase error <1.5 over 3 octaves without requiring any calibration or tuning. The receiver shows a flicker noise corner as low as 40Hz, achieving a dynamic range of 106 dB.
