  • Abstract
    This paper presents a 4th-order Chebyshev HPF in 65 nm CMOS process with programmable gain and corner frequency to support ADSL and 5/6 band VDSL applications. The HPF improves noise performance by applying capacitive feedback and feedforward in the filter. It achieves a 70 dB MTPR and -161 dBm/Hz (2.8 nV/radicHz) input referred noise for ADSL mode. An IM3 of -80 dBc at 10 MHz is measured for VDSL mode.
