Abstract—This paper presents a fourth-order Chebyshev high-
pass filter (HPF) in 65 nm CMOS process with programmable gain
and corner frequency to support ADSL and 5/6 band VDSL ap-
plications. The HPF improves noise performance by reducing the
number of cascaded stages in the receive path and using capaci-
tive feedback to minimize the total number of resistors in the filter.
The choice of filter a
