i have a question here...
isn't a comparator just a bunch of cascaded amplifiers?
I've made a comparator formed of cascaded common src stages, with an input differential stage , with single o/p. and it's working just fine, producing a perfect square wave at the o/p when the differential i/p is in range of 100s of microvolts...
so, what's the difference between this comparator and an opamp like 741, for instance?
i think that 741 or other opamps are nothing but comparators if used in open loop configuration.
i have another question, can my simple multistage amplifiers comparator act as a gain-controlled amplifier with -ve fb configurations like the various opamp circuits :?:
thanks
