Abstract

This paper describes a practical electro-optic sampler of the measuring-microscope mode for noninvasive measurements of voltage waveforms at points internal to a GaAs integrated circuit. A 360° linear sweep phase shifter is used to provide the scanning delay of the sampling point in time, and was typically demonstrated in measuring the dynamic frequency divider circuit. In addition to the characterization internal to GaAs ICs, the overlap of the electrical signal field in an integrated circuit and the interference effect on the signal voltage calibration are also investigated.
