5.5 An n-channel MOSFET operating with vOV = 0.5 V exhibits a linear resistance rDS = 1 kΩ when vDS is very small. What is the value of the device transconductance parameter kn? What is the value of the current iD obtained when vDS is increased to 0.2 V? to 0.5 V? and to 1 V?
2 mA/V2; 0.16 mA; 0.25 mA; 0.25 mA
