Determine vGS vDS and iD for the transistor amplifier of Figure 119 in the text Assume

 Determine vGS , vDS , and iD  for the transistor amplifier of Figure 11.9 in the text. Assume VDD  = 12 V; RD  = 10 ks-2R1  = R2  = 2 Ms-2RS  = 10 ks-2VT  = 1 V; K = 1 mA/V2.

11.17      The power MOSFET circuit of Figure P11.17 is configured as a voltage-controlled current source. Let = 1.5 A/V2 and V= 3 V.

a.    If V= 5 V, find the range of Rfor which the VCCS will operate.

b.    If RL  = 1 s-2, determine the range of VG  for which the VCCS will operate.
