ABSTRACT
  • The 1/f noise can be reduced through a switched
    gate.
  • The flicker noise generated is inversely
    proportional to the gate switching frequency.
  • The novel tail transistor topology is compared to
    the two popular tail transistor topologies.

4
INTRODUCTION
  • The tail transistor may be the largest
    contributor to the phase noise in a VCO.
  • The noise sources from the tail transistor can be
    categorized into high-frequency noise source and
    low-frequency noise source.
