The phenomenon known as "Early Effect" in a bipolar transistor refers to a reduction of the effective base-width caused by

  1. electron-hole recombination at the base
  2. the reverse biasing of the base-collector junction
  3. the forward biasing of emitter-base junction
  4. the early removal of stored base charge during saturation-to-cutoff switching
