The circuit parameters are VDD = 2.2 V, R₁ = 355 ks2,R₂ = 245 k2, and Rp = 100 ks2. Find ID, VGS, and VDs. (Ans. ID = 7.52 μµA,VGS=0.898 V, VDs = 1.45 V)When the bias condition may not be obvious, which means that we have to do aninitial guess:1. Assume that the transistor is biased in the saturation region, in which case VGS> VTN ID>0, and Vos ≥ Vos(sat)2. Analyze the circuit using the saturation current-voltage relations.3. Evaluate the resulting bias condition of the transistor. If the assumedparameter values in step 1 are valid, then the initial assumption is correct.4. 4. If the initial assumption is proved incorrect, then a new assumption must bemade and the circuit reanalyzed. Step 3 must then be repeated.
