Design and Simulation of a Novel Nano Structure Quantum Well Voltage Regulator to have a Lower Regulated Voltage

摘要

In this paper we present a novel nano structure quantum well voltage regulator (QWVR) to regulate a voltage in very low voltages, that can be used in low voltage and low power IC's. This structure is based on the double electron layer tunneling transistor (DELTT). We used the depletion mode MOSFET in series with the DELTT and before it to eliminate higher states of resonant tunneling current. Simulation results show that the voltage regulation is occurred around 0.3v. A desired regulated voltage is obtained with a specific value of the thickness and the concenturation of the GaAs and the AlGaAs epilayers. To simulating the proposed structure, the stationary viscous quantum hydrodynamic model has been used.
