The circuit parameters have the following values: VS=4V and R=1kΩ, and the ExpFET parameters are: K=1mA, VT=1V and VN=1V.

Given that vIN=0.5V, what is the value of vOUT in Volts?

q2 p1: Vs as vin<vt
p2: v0 = vs-kr(e^((vin-vt)/vn)-1)
p3: vin = ln(vs/2kr +1)vn+vt
p4: vin=sqrt(vs/kr)+vt
p5: -kre^((vin-vt)/vn)
p6: -kr(vin-vt)


vs=4.5 r = 1k k =1mA vt=1 vn=1
1: 4.5 vin=0.5
2: 2.7818 vin=2
3: 2.1786 vo=vs/2
4: 3.1213 vo=vs/2 mosfet
5: -2.7182 vin=2 
6: -1 vin=2 mosfet

Just change the values with yours
