Current-Mode High-Precision Full-Wave Rectifier Based on Carbon Nanotube Field Effect Transistors

Carbon nanotube field effect transistors (CNTFET) with extraordinary properties such as high carrier mobility, excellent thermal conductivity and high current carrying capability could be seen as a good replacement for CMOS technology. By connecting gate and drain in carbon nanotube field effect transistor, this device operates as a diode, similar to a diode-connected transistor in a silicon device. This paper presents a novel design of a high performance current mode (CM) precision full-wave rectifier by using just four diode-tied carbon nanotube field effect transistors. All simulations have been performed in HSPICE, and show that this circuit has an excellent performance at high frequencies.
