Electrically Configured Analog Signal Modulation and Logic Operation with Dual-Doped RFET

Abstract

This paper proposes and analyzes various configurations of dual-doped (DD) reconfigurable field-effect transistors (RFET) that enable operation as p-type, n-type, and ambipolar operational modes through electrical connections of electrodes. This versatility, achieved through a single DD-RFET, is harnessed by demonstrating applications for analog design (frequency-doubling, phase-reversal, and phase-following applications) and logic operations (NOT, OR, NAND, and XOR). DD-RFET enables the realization of analog and logic blocks through a single device paving the way for area-efficient multifunctional processors. © 2002-2012 IEEE.
