Özet

In this study, an ultra low-voltage, ultra low-power dynamic threshold voltage MOS transistor (DTMOS)-based CCII design has been presented. The proposed circuit operates under +/- 0.2 V symmetric power supply. Consisting of only eight transistors, it consumes only 214 nW power while all transistors are working in the subthreshold region. It has a 570 kHz 3 dB-bandwidth from X terminal to Y terminal for the voltage gain. TSMC 0.18 im process technology is used in the design of CCII block which is then employed in a band-pass filter configuration. In order to further investigate its performance, real speech signals are fed to the filter and close agreement is found between theoretical study and simulated responses.
