DOI: 10.1109/tthz.2018.2884612
Abstract: Sub-mm circuit design requires accurate on-wafer characterization of passive and active devices. In industry, characterization of these devices is often performed with off-wafer short-open-load-thru (SOLT) calibration. In this paper, the validity of this characterization procedure… read more here.
