Vo=(R2/R1)(V2-V1)
You use a thermocouple as the input to the amplifier circuit.

Differential amplifier ANSWER: A differential amplifier is an op amp. If any amplification is required a preamplifier is used mainly to cut the white noise and improve the input impedance
The differential voltage is amplified using the instrumentation amplifier.This is the inference we know from instrumentation amplifier...
Vo=(R2/R1)(V2-V1)
1.differential amplifier 2.operational amplifier 3.instrumentation amplifier 4.chopper amplifier 5.isolation amplier
a differential amplifier helps to increase the CMRR which in turn helps avoid unwanted signals that couple into the input to get propagated. IT also helps to increase the signal to noise ratio. furthermore it provides larger output voltage swings.
here we r going to see about the derivation of the reset gain... the instrumentation amplifier which has got two stages that is gain stage and differential stage
A instrumentation amplifier is a special purpose linear amplifier used to amplify low level signals. These are used in many industrial and medical applications.

for better amplification ...by instrumentation amplification we get the output admittance will be more
An op amp is made from transistors, resistors and capacitors. It is enclosed in a "chip". A basic instrumentation amp is made of 2 op-amps. you can't have a single op-amp perform as good as a instrumentation amp, although it can perfrom the same task. An i-amp has much better CMMR (common-mode rejection) and a higher input impedance.
