An event-based ECG-monitoring and QRS-detection system based on level-crossing sampling

A complete event-based ECG monitoring and QRS-detection system is designed and implemented which is working based on level-crossing sampling. The system contains an analog front-end including a three-stage band-pass filter and variable-gain amplifier, a single-path level-crossing analog-to-digital converter (SP-LCADC) and a QRS-detector digital core which… (More)
