Just wondering how would one design a comparator using just discrete BJTs.
Emitter coupled pair like the one in attachment?
I've been playing with this since yesterday. How do you fix the gain of this ckt.
In the ckt, how do I overcome the min Vbe requirement of Q1,Q2.
For a TTL output comparator a BJT configured as a CE amplifier with Vcc=5v would work?
I just need something that works and also simple enough to understand.
Ok I modified your circuit to make about the simplest "comparator" possible out of a few discrete components.huh. Here it is.
