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<;8.6dB, PidB >;-28dBm, IIP3>;-12dBm and IIP2>;22dBm over a band from 1.75 to 15 GHz. 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 40 Hz, achieving a dynamic range of 106 dB.
