  • H03F3/26 - Push-pull amplifiers Phase-splitters therefor
  • H03F3/45071 - with semiconductor devices only
  • H03F3/45479 - characterised by the way of common mode signal rejection
  • H03F2203/45008 - the addition of two signals being made by a resistor addition circuit for producing the common mode signal
  • H03F2203/45051 - Two or more differential amplifiers cascade coupled
  • H03F2203/45072 - the common mode voltage or current signal being added to the tail circuit of the differential amplifier
  • H03F2203/45074 - A comparator circuit compares the common mode signal to a reference before controlling the differential amplifier or related stages
  • H03F2203/45076 - the resulting deducted common mode signal being added to or controls the differential amplifier, and being a current signal
  • H03F2203/45134 - the whole differential amplifier together with other coupled stages being fully differential realised
  • H03F2203/45202 - the differential amplifier contains only resistors in the load
  • H03F2203/45212 - the differential amplifier being designed to have a reduced offset
