A 28-MHz wideband switched-capacitor bandpass filter with transmission zeros for high attenuation

A 28-MHz wideband switched-capacitor (SC) bandpass filter employs an N-path technique and implements transmission zeros in the transfer function to achieve high attenuation. A modified SC biquadratic filter architecture is proposed to achieve high-speed operation. Implemented in a 0.35-/spl mu/m CMO...
