WebMay 22, 2024 · One of the more useful BJT device plots is the family of collector curves. This is a series of plots of collector current, IC, versus collector-emitter voltage, VCE, at varying levels of base current, IB. To generate these curves we drive the base terminal with a fixed current source establishing IB. WebThe forward biased from base to emitter narrows the BE depletion region while the reverse bias from the base to collector widens the BC depletion region. However, due to the flow of currrent in the base and the abundance of current carriers int the collector (heavily doped), the excess carriers from the emitter to the collector (through the base).
