Plessey Semiconductors Electric Potential
Integrated Circuit (EPIC) product line
targets a range of applications.
The PS25101 is an ultra high impedance
solid state ECG (electrocardiograph)
sensor. It can be used as a dry contact
ECG sensor without the need for
potentially dangerous low impedance
circuits across the heart. The resolution
available is as good as or better than
conventional wet electrodes.
The device uses active feedback
techniques to both lower the effective input
capacitance of the sensing element (Cin)
and boost the input resistance (Rin). These
techniques are used to realise a sensor
with a frequency response suitable for both
diagnostic and monitoring ECG
applications. The total voltage gain of the
system is a function of both the input
coupling capacitance (variable) and the
internal sensor configuration.

APPLICATION OF THE ECG SENSOR
Because of the large coupling capacitance to the body (around 1nF) the EPIC sensor’s internal electrometer can be
used in differential mode to recover true surface potential ECG signals from the surface of the skin.
