www.st.comPower MOSFETs and IGBTs are simply voltage driven switches, because their insulated gate behaves like a capacitor. Conversely, switches such as triacs, thyristors and bipolar transistors are “current” controlled, in the same way as a PN diode. 2.2 Driving a gate As shown in figure 2, driving a gate consists of
Power MOSFET Basics - Alpha and Omega Semiconductor
www.aosmd.comFor power MOSFETs, it is usually measured at the drain-source current of 250uA. Gate oxide thickness and doping concentration of the channel can be used to control the V . Typically, 2~4V is designed for gate drive of 10-15V. With the scaling down of the CMOS technology, the gate
AND9093 - Using MOSFETs in Load Switch Applications
www.onsemi.comUsing MOSFETs in Load Switch Applications Introduction In today’s market, power management is more important than ever. Portable systems strive to extend battery life while meeting an ever increasing demand for higher performance. Load switches provide a simple and inexpensive method for the system to make the appropriate power management
Sub-threshold MOSFET Operation - MIT OpenCourseWare
ocw.mit.eduMOSFETs operating in strong inversion when we bias as close to threshold as possible. This current limits how close we can get. 2. It is a major source of power dissipation and heating in modern VLSI digital ICs. When you have millions of MOSFETs on an IC chip, even a little bit of current through the half that are supposed to be "off" can add up
