Abstract

In this paper, we investigate the effect of two calibration errors, probe placement and capacitance per unit length, on transistor characterization from 220 GHz to 325 GHz on both a microstrip and an inverted coplanar waveguide with a via stitched ground plane (CPW-G) calibration kit. We find the capacitance per unit length errors are greater for the microstrip calibration than for the CPW-G calibration. These findings have critical ramifications for transistor characterization and modelling, and active circuit design.
