| 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, P1~{dB}> -{\ {28}}~{\ {dBm}}, \ IIP3 >-12~\ dBm and \ IIP2>22~\ 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 < 1.5 ^\circ over three 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. [ABSTRACT FROM AUTHOR] |
