Transcribed Image Text:
An n-MOSFET for which W/L = 10, where W is the device width, and L is the source-to- drain distance, the oxide thickness and dielectric constant are tor= 100 nm and € = 3.9, and the hole mobility near the surface pe = 100 cm²/(V s). The device is to be used as a controlled resistor. . (a) Calculate the surface charge density in the inversion channel that is required for the MOSFET resistance between the source and the drain to be 10k at low values of VD<V(sat). Note that at small drain voltage, the inversion-layer surface charge density Q is independent on the coordinate x. (b) What gate voltage in excess of the threshold voltage, AV = VG - Vr, is necessary to maintain the inversion surface charge density found in part (a)?
