I have designed a low battery detector circuit using low power comparator MCP6541 for a 4.2V Li-ion battery. This circuit checks whether the battery voltage if the battery voltage is lower than 3.5V then it will glow LED. Check the circuit below.
The circuit is working properly but the...
i am trying to get a comparator working with Hysteresis. A 500mV is the target between Vlth 2v and Vhth 2v5.
Can somebody please help me with the Hysteresis part with an explanation for the attached LTSpice simulation.
How to make a full bit (2bit) comparator circuit using ONLY nand gates. I was able to do a 1bit comparator using only NAND gates, but how about for 2 bit, 4 bit? Wouldnt it be really large. I'm not sure if my class expects us to draw this out. we can't even use xor gates or inverters.
