Unformatted text preview: f gure shows a MOSFET bias circuit. Given: V + = 24V , R D = 11k , R G = 100k , R S = 1 . 2k , K = 10 S / V 2 , and V TO = 1 . 8V . (a) Solve for V GG and R GG . V GG = V + I D R D R GG = R G + R D (b) Write the loop equation for the gate-source loop and use it to solve for I D assuming the MOSFET is in its saturation state. V + I D R D = r I D K + V TO + I D R S = I D ( R D + R S ) + 1 K p I D + V TO V + = 0 = I D = 1mA (b) For the value of I D , check to verify that V DS > V GS V TO for the MOSFET to be in the saturation state. V DS = V + I D R D ( I D R S ) = 11 . 8V V GS V TO = r I D K = 10V 1 2...
