MOSFET Operating Regions

NOTE: The images in the article are taken from Behzad Razavi’s “Design of Analog CMOS Integrated Circuits” Book. MOSFET type transistors consist of four terminals in total, namely gate, drain, source and body terminals. Unlike the base current of BJT transistors, MOSFETs have no gate current. There are two types of MOSFETs, N and P type. In N-type transistors, after the threshold voltage (Vth) is applied between the gate and source terminals of the transistor, the excess electrons in the N-doped region to which the source terminal is connected are… Daha fazlasını oku »MOSFET Operating Regions
