Abstract :
The authors describe the design and CMOS realisation of a new g m-C amplitude equaliser for correcting sinc(x) distortion in video D/A converters. Simulated and measured results demonstrate how the equaliser is used to correct distortion in D/A converters with Fs =13.5 MHz to ⩽0.08 dB ripple over 5 MHz bandwidth. Fabricated using a 0.8 μm CMOS process, the equaliser occupies 0.7 mm2 and dissipates 20 mW from a 5 V supply
