MOS Transistor Theory
MOS Transistor Theory • Study conducting channel between source and drain • Modulated by voltage applied to the gate (voltage-controlled device) • nMOS transistor: majority carriers are electrons (greater mobility), p-substrate doped (positively doped) • pMOS transistor: majority carriers are holes (less
