The Early effect in bipolar junction transistors is named after Jim Early, who first characterized it and published a paper on it in 1952. The Early effect in bipolar junction transistors is due to an effective decrease in the base width because of the widening of the base-collector depletion region, resulting in an increase in the collector current with an increase in the collector voltage. The same type of length modulation in MOSFETs is also commonly referred to as Early effect.
