  • Title: Bootstrapped two-electrode biosignal amplifier.
    Author: Dobrev DP, Neycheva T, Mudrov N.
    Journal: Med Biol Eng Comput; 2008 Jun; 46(6):613-9. PubMed ID: 18266016.
    Abstract:
    Portable biomedical instrumentation has become an important part of diagnostic and treatment instrumentation. Low-voltage and low-power tendencies prevail. A two-electrode biopotential amplifier, designed for low-supply voltage (2.7-5.5 V), is presented. This biomedical amplifier design has high differential and sufficiently low common mode input impedances achieved by means of positive feedback, implemented with an original interface stage. The presented circuit makes use of passive components of popular values and tolerances. The amplifier is intended for use in various two-electrode applications, such as Holter monitors, external defibrillators, ECG monitors and other heart beat sensing biomedical devices.
