An on-chip 100 GHz-sampling rate 8-channel sampling oscilloscope with embedded sampling clock generator

Abstract

An on-chip 8-channel sampling oscilloscope macro for signal integrity checking uses a 0.13 /spl mu/m CMOS process. It contains a phase-interpolated sampling clock generator for 100GHz sampling, charge-sharing sampling heads, and ESD-tolerant decoupling capacitors for noise-immune measurement.
