Op-Amp Comparator

jojo February 24, 2014 14 Comments
In this post we will be discussing about the op-amp as a comparator.We have already discussed other applications of the op-amp in rectangular wave form generator circuits like astable (or free-running) multivibrators, monostable multivibrators (or one-shot) and bistable multivibrators (or flip-flops). To...

Monolithic IC-Component Fabrication

jojo May 21, 2014 1 Comment
The outstanding feature of an IC is that it comprises a number of circuit elements insepa¬rably associated in a single small package to perform a complete electronic circuit. We shall now see how various circuit elements (such as transistors,...
