CSDG MOSFET Based Linear Voltage Regulator: A Mixed Signal Device Perspective

Abstract

Various circuitries that make up an electronic communication system requires different voltage signal to power them, and this comes from voltage sources that are higher than the required. A voltage regulator is required to do the conversion and maintain that stable output signal. However, some system requires different voltages for its different outputs. Due to this need, the design of a voltage regulator with different voltage inputs and multiple output becomes imperative. In this research work, the Cylindrical Surrounding Double-Gate (CSDG) MOSFET has been employed to design linear voltage regulator and its efficiency has been verified. This design proves to have high efficiency, utilizes small device area, and reduces the degrading of devices due to constant system reset caused by feedback.
