摘要：The design of CMOS analog circuitry for acquiring 12 lead ECG is presented. The existing methodsemploy separate multiplexers and associated circuitry for signal acquisition operating at typical voltage of± 5V. The proposed system employs dynamic threshold logic to achieve low power, wide dynamic rangegood linearity with a supply voltage of 0.4V. The power dissipation obtained was 22.12μW. Utilizing thedynamic threshold logic the proposed circuitry is implemented with 0.18μm CMOS technology. This ECGsignal processor is highly suitable for wearable applications of long term cardiac monitoring.
