This letter proposes a novel application of asymmetric (double-gate) tunnel field-effect transistors (asymmetric TFETs) as a frequency multiplier. Work-function tuning of an asymmetric TFET was used to demonstrate symmetric ambipolar transfer characteristics by TCAD simulation. Unlike the conventional balanced FET-based multiplier, the asymmetric TFET design needs only one transistor for rejecting odd harmonics. Advanced design system simulations are used to compare the performance of an n-type FET and an asymmetric TFET frequency multiplier.
