    Biography of Onno W Purbo. Please Share this article is useful! Onno W Purbo. Born Aug Onno's father, Hasan Poerbo, ITB is a professor in the environmental field that much in favor of the little people. Onno entered ITB majoring in Electrical Engineering class Equations and parameters provided are checked continuously against the reality of silicon data, making the book equally useful in practical transistor design and in the classroom. Every chapter has been updated to include the latest developments, such as MOSFET scale length theory, high-field transport model, and SiGe-base bipolar devices. Bipolar transistors consist essentially of two mutually connected p-n junctions with the layer sequence n-p-n or p-n-p. The connections of the bipolar transistor are emitter (E), base (B) and collector (C). While emitter and collector have the same doping, the very thin base layer in-between is doped contrarily.
