Abstract

In
this study, p-MOSFETs in floating current source circuit are converted to
dynamic threshold voltage MOSFET structure and a second order notch filter
application is carried out by using the DTMOS based FCS circuit. The proposed
model is simulated in LTSPICE simulator by using Taiwan Semiconductor
Manufacturing Company 0,18μm CMOS technology. DTMOS structure allows the
operation of the circuit at lower power about 4,95nW. Operating frequency of
notch filter consisting of the DTMOS-FCS circuit is set up to suppress the
undesirable effects of power-line interference on the electrocardiograph
signals.
