Instrumentation Amplifier

An electrocardiography (ECG) machine is an essential piece of medical equipment used to monitor the electrical activity of the heart. It operates by detecting small electrical changes on the skin that result from the depolarization of the heart muscle during each heartbeat. However, these signals are in the microvolt range and can be easily overwhelmed by noise or interference.
To overcome this challenge, an ECG machine utilizes an instrumentation amplifier. This specialized amplifier is...

Area of Science:

  • Experimental Physics
  • Materials Science
  • Electrical Engineering

Background:

  • Gas gun shock experiments require precise measurement of electrical properties in metals.
  • Low-resistance metals present challenges due to high currents and resulting high common-mode voltages.
  • Existing amplifiers may lack the necessary bandwidth or common-mode rejection for these demanding applications.

Purpose of the Study:

  • To develop a high-bandwidth differential amplifier specifically for gas gun shock experiments.
  • To enable accurate measurement of small voltage signals in the presence of large common-mode voltages.
  • To improve the characterization of low-resistance metals under dynamic conditions.

Main Methods:

  • Designed a differential amplifier circuit with a bandwidth up to 1 GHz.
  • Implemented a high common-mode rejection capability (250 V).
  • Utilized a four-point probe-like technique for target voltage measurement during high-current flow.

Main Results:

  • The amplifier successfully measures signals as low as 50 mV with a 10 ns duration.
  • Achieved a common-mode rejection of 250 V, crucial for the experimental setup.
  • Demonstrated the amplifier's ability to withstand significant common-mode DC voltage.

Conclusions:

  • The developed differential amplifier is suitable for high-bandwidth gas gun shock experiments on low-resistance metals.
  • The amplifier's design effectively addresses the challenge of measuring small signals amidst large common-mode voltages.
  • This advancement facilitates more accurate conductivity measurements and material characterization under extreme conditions.
