Instrumentation amplifier

  
Three-amplifier circuit consumes only 135 /tW of power from a ±1 V power supply. With a gain of 101, the instrumentation amplifier is ideal in sensor interface and biomedical preamplifier applications
Instrumentation amplifier - schematic

The first stage provides all of the gain while the second stage is used to. provide common mode rejection and double-ended to single-ended conversion.
