Abstract:
1. A method, comprising: providing a first body-contacted silicon-on-insulator (SOI) metal-oxide-semiconductor-field-effect-transistor (MOSFET) device having a drain region, a source region, a body region separating the drain region from the source region, and a gate disposed above the body region, the first body-contacted SOI MOSFET device coupled to a sensing circuit having an input and an output, wherein the input of the sensing circuit has a high impedence and the output of the sensing circuit has a low impedence, wherein the body region of the first body-contacted SOI MOSFET device is coupled to the input of the sensing circuit to form a floating body node having a voltage Vbody; measuring the voltage at the output of the sensing circuit, the voltage at the output of the sensing circuit represented as Vout; and determining the voltage of the floating body node Vbody from the voltage measurement at the output of the sensing circuit Vout, wherein Vbody=2*Vout.
