WebOct 16, 2014 · Common emitter output characteristics of NPN-BJT 35. Early Effect An increase in magnitude of collector voltage increases (reverse bias) the space charge width increase at the output junction diode (C-B junction). Such action causes the effective base width ‘W’ to decreases. A phenomenon know as ‘Early Effect’ WebFeb 3, 2024 · A large collector base reverse bias is the reason behind the early effect manifested by BJTs. As reverse biasing of the collector to base junction increases, the depletion region penetrates more into the base, as the base is lightly doped. This reduces the effective base width and hence the concentration gradient in the base increases.
