Abstract :
This paper presents the design of an active-RC filter with variable bandwidth and channel-selectivity characteristics for wireless communication applications. The topology of this filter is the 5th-order low pass type. The 3-dB bandwidth is programmable at 10, 20 and 40 MHz. The filter is fabricated in a 0.13-mum CMOS technology and dissipates 13.2 mW for a supply voltage of 1.2 V.
