An 80-Msample/s video switched-capacitor filter using a parallel biquadratic structure

This paper describes a fifth-order, low-pass switched capacitor filter for video applications. It has a 4-MHz cutoff frequency and uses a parallel biquadratic structure with double sampling to achieve an 80-MHz input sampling rate in a 2-/spl mu/m CMOS process. The prototype filter is fully differential, occupies an active area of 11 mm/sup 2/, and dissipates 190 mW.<
