A 0.5 μA/Channel front-end for implantable and external ambulatory ECG recorders

There is an increasing demand for low power, low voltage, and small size analog readout bio-potential systems. This paper presents an analog front-end for measuring the intra-cardiac signals in implantable and also external ambulatory ECG cardiac recording applications. The analog front-end benefits from voltage to frequency conversion...

A 0.6V, 1μW, low-power low-noise instrumentation amplifier for ECG/BioZ measurement in 40nm CMOS

This thesis presents a low-power low-noise instrumentation amplifier designed to be implemented in 40 nm CMOS technology and operating from a 0.6 V supply, intended for use in electrocardiogram (ECG) and bio-impedance (BioZ) signal acquisition. This instrumentation amplifier has one ECG channel, one BioZ channel and allows both signals to be...
