Abstract :In this work, a band pass filter circuit consisting of Current Differencing Transconductance Ampliﬁer insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
Keywords : Current Differencing, Transconductance Ampliﬁer
