WebApr 6, 2024 · What is Early effect in BJT Mcq? A large collector base reverse bias is the reason behind the early effect by the 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 is known as the Early effect. What happens at early voltage? 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’
