In
this work, a band pass filter circuit consisting of Current Differencing
Transconductance Amplifier (CDTA) structure, working in the biomedical signal
frequency range, is proposed and simulation results are obtained via LTSPICE
program. PMOS transistors in the proposed CDTA filter circuit are made with
Dynamic Threshold Voltage MOS (DTMOS) structures instead of traditional
MOSFETs. LTSPICE simulations of the proposed circuits give results that agree
well with the ideal results. The proposed CDTA filter circuit thanks to the
usage of DTMOS transistors operates at a supply voltages of ± 0.4V and power
dissipation is approximately 90nW.
