Suggest me some analog circuits for voltage comparison

[test_out]

Hi,

Can any one suggest me some analog circuit for voltage comparation?
This comparator will compare a voltage input and a reference input and give me the logic level?

Thanks

Hi
You can use directly a op-amp with single supply (0V-5V) or use Triger Smith circuit.

make IC 741 as a comparator or as schmitt trigger....both will will act as comparator

Re: comparator!

To design a comparator, you need to have high gain amplifer. To achieve this, design a folded cascode + gain boost architecture. Then this amplifier have to be followed by a digital inverter buffer to determine your output logic level for input voltage comparison.

I suggest you to first read this:

comparator!

In Allen and Holberg book there is many type of comparator..from two stgae to hysterisys even latch type.

i attched a type of comparator

it can compare voltage but how small the different volatge it can compare@resolution is up to u to design and selecting the transistor size.
