Abstract
A 36/44-MHz wide-band switched-capacitor (SC) band-pass filter is proposed for cable-TV tuner systems. The 14th-order SC biquadratic filter employs 2-path technique to achieve high attenuation and wide bandwidth at high frequency. Implemented in a 0.18-mum CMOS process, the filter measures center frequencies of 36 MHz and 44 MHz with a bandwidth of 5.0 MHz and 6.2 MHz, respectively. Adjacent-channel attenuation of -58 dBc and pass-band ripple of less than 0.6 dB are achieved.
