comparison between cmos and bipolar technologies

comparison between cmos and bipolar technologies
cmos technologies:
  • low static power dissipation
  • high input impedance
  • scalable threshold voltage
  • high noise margin
  • high packing density
  • high delay sensitivity to load(fan out limitations)
  • low output drive current
  • low transconductance(gm)
  • bidirectional capability
  • drain and source are interchangeble
  • a near ideal switching device
  • fully restored logic levels

bipolar technology:

  • high power dissipation
  • low input impedance
  • low voltage swing logic
  • low packing density
  • low delay sensitivity to load
  • high output drive current
  • high transconductance
  • unidirectional
