Threshold Voltage and Source to Body Voltage Analysis in Mosfets

The threshold voltage of the MOSFET is the minimum voltage required to turn on the MOSFET device. The MOSFET threshold voltage can be increased or decreased by applying the proper body potential. The body voltage is known as body bias voltage. The possible ways of body biasing are explored in this chapter. The impact of the various body bias voltages is studied on the MOSFET input characteristics and output characteristics of the MOSFET device. The MOSFET under study are 45nm channel length. This is also known as 45nm Technology. The body bias is studied in PMOS and NMOS devices. The active body bias approach is explored. Reverse body bias is explored to increase the threshold voltage of the PMOS and NMOS devices.
