This Presentation is about Digitals Switching in MOSFETS. In this lecture working of MOSFETS is explained and also shows how MOSFETS are used in Power switching.
3. CMOS(Complementary MOS)
Technology to construct ICs, Logic gates etc.
pMOS:
• Used to make Pull Up Networks(PUN)
• In PUN “+” suggests series and “.” suggest parallel
• Passes 1(VDD)
• 0 to gate will ON
• 1 to gate will OFF
nMOS:
• Used to make Pull Down Networks(PDN)
• In PUN “.” suggests series and “+” suggest parallel
• Passes 0(ground)
• 1 to gate will ON
• 0 to gate will OFF
8. MOSFET In Power Switching
MOSFET has
Positive temperature coefficient which prevents thermal runway.
Low Power Losses
Fast switching Speed
MOSFETs are used for
Motor Control
DC to AC Conversion
DC to DC Conversion
Load Switching
