Design of an ECG Amplifier

Multi-stage bioinstrumentation amplifier with noise filtering

Course: EE230 - Analog Lab

Duration: Apr 2024

  • Assembled a 3-stage ECG amplifier with leg drive section to minimize common-mode interference, biasing an INA fed by the left and right hand
  • Implemented low pass and notch filters to reduce high frequency and line noise
  • Plotted and analyzed the readings, using LTSpice for circuit simulations and parameter tuning
