Electrocardiogram
Dec 2025
The goal of this project is to design, simulate, and build a 4-stage ECG device composed of a bandpass filter, an instrumentation amplifier, a notch filter, and an amplifier. This is an exercise in analog circuit design and simulation using LTSpice, as well as hands-on prototyping with circuit assembly and testing.
About
- Designed full circuit, including 0.05 - 100 Hz bandpass, 60 Hz notch, variable gain.
- Simulated Bode plots on LTspice.
- Tested full device with oscilloscope, signal generator.
