Abstract

The paper presents the design of a wide-band active-RC filter with a fast tuning circuit for wireless communication receiver applications. The filter topology is the 5th-order Chebyshev-II lowpass filter type and the programmable bandwidth can be extended up to 10MHz while the stopband attenuation larger than 40dB is obtained. The Successive Approximation Register (SAR) scheme is incorporated for a prompt on-chip tuning operation that should be needed for compensating RC variations. The filter is fabricated in a 0.18-μm standard digital CMOS technology and dissipates 20.7mW for a supply voltage of 1.8V. The measured 3rd-order harmonic input intercept point (IIP3) is larger than 32dBm.
