Hi Everybody,

Can any one send me a desing of a high precision Comparator. I am unable to find a good circuit.It would be great if some one send me a project to the following address.

pavan_p1@yahoo.com

Thank You,
pavan

 

How high is "high"? What is the power supply, load, speed, etc?

These are the details of the comparator

Description: small ( npn, pnp) general purpose Comparator.
Bandwidth: 35MHz
Risetime: 8nS
Gain: 52dB
Ibias: 5uA
Vout: 0.4 to 5V
Input CM Range: +/- 2.5V
PSSR: 70dB
CMRR: 80dB (f<5MHz)
Vos: 2mV (3 sigma)
Power Supplies: +/- 5V
Power Dissipation: 36 mW

 

Sounds like a homework assignment.

Its not an Homework problem
I am doing this project for a client
but the thing is i have never done comparator.

 

OK. Are you planning on using discrete transistors, or is this an integrated circuit?
LM360 is very close to what you are looking for, and it already exists.

out of curiosity .. y u re-invent the wheel??

 

I agree that it looks like a homework assignment, I can't see any client giving such a project in such a way - and if they did?, I would tell them to go else where!.

I betcha that the client is a student. :lol:

Thanks to all the members who has participated in this post.

I am able to design the circuit.

 

He just needed to be pointed to the LM360. :lol:
