This IP is a high precision, ultra-low power biopotential analog frontend (AFE) readout circuit designed for wearable and implanatable medical devices.
It provides clinical-grade electrocardiogram (ECG) waveforms and QRS detection (optional), with nanopower consumption for longer battery life, also crucial to ensure continuous monitoring (150 nW at 4 kHz).
The single biopotential channel is AC coupled and has optional AC leads-on detection during shutdown mode (< 2 nW).
The AFE readout circuit also features high input impedance, high CMRR, and input noise < 2 ????Vrms over standard ECG bandwidth.
This AFE readout circuit is designed as a BOM-free and compact component to enable less obtrusive cardiac monitoring devices.
Users can select the input signal dynamic and the frequency cut-off to suit different types of applications.
The AFE readout circuit can be combined with analog and digital support functions to create a complete cardiac monitoring system.
