Abstract：

Existing　commercial　pacemakers　only　provide　single-chamber　pacing　and　cannot　achieve　multi-chamber　sequential　pacing.　Conduction　Intracardiac　Communication(CIC)　has　the　characteristics　of　low　power　consumption　and　high　security,　which　is　very　suitable　for　communication　between　multi-chamber　leadless　pacemakers.　Because　the　pacemaker　needs　to　be　implanted　into　the　heart,　which　limits　its　volume,　power　consumption,　and　other　related　parameters,　and　the　super-regenerative　circuit　has　its　low　power　consumption　and　simple　circuit　structure,　the　super-regenerative　receiver　scheme　is　a　good　choice　for　intracardial　communication　where　power　consumption　is　the　main　problem.　In　this　paper,　a　prototype　super-regenerative　receiver　suitable　for　intracardiac　communication　is　proposed.　The　differential　instrument　amplifier　with　high　input　impedance　is　used　to　filter　out　the　external　electromagnetic　interference,　reduce　the　input　equivalent　noise,　and　improve　the　signal-to-noise　ratio.　A　super-regenerative　oscillator　and　a　filter　amplifier　circuit　are　designed　to　enhance　the　effectiveness　and　reliability　of　the　communication.　The　experimental　results　show　that　the　bit　error　rate　of　the　circuit　is　lower　than　1　×　10-5　for　the　received　signal　of　-92　dBm.　©　2023　IEEE.
