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. WebDec 31, 2024 · When the transistor heats up, this resistance goes down, and the betaDC goes up. So it takes a smaller amount of base current to make more current flow in the …
