Abstract :
A novel fully integrated preamplifier stage for cardiac activity sensing is presented. The proposed design takes advantage of the High Voltage CMOS (HV) technology properties to comply with the safety requirements of implantable devices without the addition of external decoupling capacitors. The power consumption is minimum; while the input referred noise is kept well below the minimum signal to be sensed. This first stage is a high pass filter with a cut off frequency at 75Hz, and 25db gain. Simulation results are presented, the circuit is being fabricated in a 0.6μm technology.
