Hi,
I am designing a µOhm Meter with 1uΩ in 1mΩ resolution using a 1A Current Source and a LTC2400 as the Voltage Measuring Device.What I want to know is how to design an opamp front end with low error.I need a gain of about 4.
Added after 3 hours 18 minutes:
I have designed the following Analog Front End.Can anyone tell me if it has any problems.
