Re: Why Latched-Comparator are not preferred in PWM applicat
Actually, I am using a latched comparator in my switching reg controller now. It has some very good points in its favor like a 30ns response time. But the main disadv I have noticed so far is its resolution/accuracy. It's not its strong point! More info on latched comparator: check following IEEE paper,
"Design techniques for high speed high resolution comparators" by Behzad Razavi and Bruce Wooley in JSSC Vol 27, No 12 Dec 1992.
Hope this helps!
