Abstract

This paper presents a receiver analog front-end (AFE) for 10GBase-T Ethernet system. The AFE can provide 14 dB voltage gain with 9 dB gain control range, and the gain step is 1.5 dB with +/-0.25 dB gain error. The analog front-end -3 dB bandwidth is 300 MHz. The 3^rd harmonic distortion (HD3) is lower than -50 dB. It consumes 48 mW for 1.8 V supply voltage. This AFE is fabricated in 0.18-mum 1P6M CMOS technology and the chip area is 0.88times0.82 mm².
