EE343 - Electronics II Design Project 2 Design an instrumentation amplifer such that Ad= 110 V/V. Select resistor values such that the first stage provides a gain of 11 VN (magnitude) and R, = 1 k22, and the second stage provides a gain of -10 V/V. Use supplies of V= V. = 15 V and a 50 mV pk-pk 1 kHz sine wave as your input. Show theoretical, simulated, and experimental values of Ad and Acm and the CMRR in dB. Explain any discrepancies between the values. Your typewritten report should include the following sections: introduction, design description, simulation, measurements, results, and discussion.

Explanation & Answer

attached is my answer and LTSpice file

Introduction
An instrumentation amplifier is regularly the principal organize in an
instrumentation framework. It is utilized to open up the signal delivered by a transducer,
for example, a thermocouple or a strain gage. An instrumentation intensifier is a
distinction speaker i.e., it increases the voltage contrast between its two information
terminals, neither of which is required to be a signal ground. An instrumentation
enhancer ought to have the accompanying attributes: high information protection, high
voltage pick up, and high common-mode-rejection-ratio (CMRR).
Design Description
For the instrumentation amplifier that we need to design, we have Ad  110 V / V ,
the resistor values are selected as follow: R1  1 k , R2  110 k , R3  1 k  , and
R4  110 k  . They are select in such a way that the first stage yields an increase of

11 V / V (magnitude) and Rl  1 k  , and the second stage yields an increase of
10 V / V . In addition, the supplies of V  V  15 V is used and a 50 m V pk  pk 1 kHz
sine wave as the output.
The instrumentation amplifier does not experience the ill effects of the disservices
recorded above; it has high info protection and high CMRR. It is clear from the circuit
chart that the input protection seen by the source is administered by the information
protection of the operation amps utilized as a part of the circuit. The information
protection of the instrumentation amplifier is along these lines high.
The required circuit c...
