摘要

针对HDSL模拟前端，采用0.5 /spl mu/m、3.3 V CMOS技术设计了低失真5/sup /阶R-MOSFET-C贝塞尔滤波器。该滤波器通过片上调谐电路在488 kHz和335 kHz的截止频率附近线性可调。制造的原型显示线性调谐和THD<-75 dB的100 kHz信号。

A low distortion linear-tunable continuous-time 488 kHz fifth-order Bessel filter

For an HDSL analog front end, a low distortion 5/sup th/ order R-MOSFET-C Bessel filter was designed in a 0.5 /spl mu/m, 3.3 V CMOS technology. The filter is linearly tunable around cutoff frequencies of 488 kHz and 335 kHz by an on-chip tuning circuit. The fabricated prototypes show linear tuning and a THD<-75 dB for a 100 kHz signal.
