• G(m)-C filters
• analog filters
• low voltage circuits

This paper proposes a 3rd-order g(m)-C filter that operates with the extremely low voltage supply of 0.5 V The employed transconductor is capable for operating in an extremely low voltage power supply environment. A benefit offered by the employed transconductor is that the filter's cut-off frequency can be tuned, through a dc control current, for relatively large ranges. The filter structure was designed using normal threshold transistors of a triple-well 0.13 mu m CMOS process and is operated under a 0.5V supply voltage; its behavior has been evaluated through simulation results by utilizing the Analog Design Environment of the Cadence software.
