A BiCMOS 5 V video reconstruction filter with sinx/x correction

A CCIR 601 video filter that integrates an input clamping circuit, a 3rd-order equalizer, a 5th-order elliptic filter with sinx/x correction, and a 75 /spl Omega/ driver achieves a 5.5 MHz (fc) lowpass filter with 60 dB SNR, 0.2% differential gain, 0.38/spl deg/ differential phase, 0.3 dB passband ripple, 20 ns group delay variation up to 0.9 fc, 43 dB attenuation at 1.45 fc in a 1.5 /spl mu/m 4 GHz BiCMOS process technology. Filter active area is 8 mm/sup 2/ and it dissipates 350 mW in a single 5 V power supply.
