Abstract

A discrete-time (DT) anti-alias filter (AAF) with clock-efficient charge-domain filter (CECDF) for high attenuation and bandwidth was developed. This AAF possesses 88.86-dB attenuation and 13-MHz bandwidth at a 600-MS/s input-clock rate (ICR) and a 100-MS/s output-sample rate. The measured gain and IIP3 are 12.2-dB and 0-dBm, respectively, consuming only 5.56-mA from a 1.36-V power supply. The chip including clock-logical circuits occupies 0.2-mm² in 90-nm CMOS logical process.
