DESCRIPTION:This is a Technical Seminar by SSCS Distinquished Lecturer\, Po
 fessor Alyosha Molnar with the following abstact:\nIn this presentation I 
 will discuss N-phase passive mixers (and their close relative the “N-pat
 h filter”) as applied to interference tolerant radio receivers.  Althoug
 h known for decades\, the advent of deep-submicron CMOS has enabled N-path
  passive mixers and filters to be scaled to GHz frequencies with surprisin
 gly good performance in both noise and linearity. I will briefly review th
 e basic operation and properties of such circuits\, and provide an intuiti
 ve analysis of the circuit and transistor properties that limit their perf
 ormance\, including insights into their response to phase noise.  Such N-p
 ath mixers\, as originally conceived\, and as implemented in the sub-10GHz
  regime\, however\, place requirements on their Local Oscillator waveforms
  that are ill-suited to the higher frequency (e.g. mm-wave) operation requ
 ired for newer standards such as 5G. I will therefore also introduce a sec
 ond set of design techniques and analytical results enable similar functio
 n at much higher frequencies.\n\nSpeaker(s): Alyosha Molnar\, \n\nVirtual:
