Parametric THz frequency multiplication using CMOS technology

Abstract

Accumulation-mode MOS varactors (AMOSVs) are considered for use in THz frequency multipliers. The superior modulation ratios and lower series loss relative to silicon Schottky diodes for a 130-nm CMOS technology are highlighted. Dynamic cutoff frequencies in excess of 1-THz are predicted. AMOSV potential for 10-dB loss, 600-GHz doublers is discussed as is an integrated 100-GHz doubler design.
