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 5/sup th/-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(More)
A low -voltage wide-band active-RC filter for wireless communication transceivers is presented. It is the 5th-order Chebyshev-II low pass filter with the bandwidth of 20 MHz. To guarantee high linear characteristic at a low supply voltage, the input common-mode level shifting circuit is added at the inputstage of the operational amplifier so that the input(More)
