Abstract :
A 1Gs/s CMOS track-and-hold for the upcoming generation of Ethernet applications (10GBASE-T) is presented. The Track-and-Hold is designed to be employed as front-end in a time-interleaved analog-to-digital converter and it is based on an open-loop architecture composed of an input buffer and a highspeed switch. The proposed Track-and-Hold, designed in a 65 nm low-power CMOS process, exhibits a total harmonic distortion lower than -80 dB and a spurious free dynamic range better than 79 dB, with a power consumption lower than 11 mW (dual supply voltages 1.2 V/2.5 V, 1.85 mA/4.22 mA).
