A N-Path Receiver With Harmonic Response Suppression

  title={A N-Path Receiver With Harmonic Response Suppression},
  author={Venkata S. Rayudu and Ki Yong Kim and R. Gharpurey},
A downconversion receiver employing a switchbased N-path filter with reduced harmonic response around the thirdand fifthLO harmonics is presented. The N-path filter is placed in a frequency-translation feedback loop that is effective at the 3rd and the 5th LO harmonics to mitigate harmonic downconversion. A pulse-width-modulated LO (PWMLO) clocking scheme is used in the feedback upconverter to reduce the noise injected around the LO harmonic at the input of N-path downconverter. The compression… Expand

Design of Active N-Path Filters
A design methodology for synthesis of active N-path bandpass filters is introduced and a 0.1-to-1.2 GHz tunable 6th-order N- path channel-select filter in 65 nm LP CMOS is introduced, achieving a “flat” passband shape and high out-of-band linearity. Expand
