Step of 6 8.003P Consider the circuit diagram shown in Figure 1. Vₛₛ Vₛₛ S S G G D D V₀ VI₀ R Figure 1 Step of 6 Notice that the value of in NMOS circuit represents the values of in PMOS circuit. Calculate the value for the maximum value of the drain to source voltage, Substitute 1.3 V for and 1.1 V for =1.1-1.3 = Therefore, the value of the voltage is, -0.2 V Step of 6 The value of the voltage should be equal to - Substitute -0.2 V for and -0.4 V for Therefore, the value of the gate to source voltage is, Step of 6 Calculate the value of the voltage at the gate terminal, Vc Substitute -0.6 V for and 1.3 V for =0.7 V Therefore, the value of the voltage is, 0.7 V Step of 6 Calculate the value of the resistance, R REF Substitute 0.7 V for and 80 for REF 0.7 R 80 8.75 Therefore, the value of the resistor R is Step of 6 Consider the expression for the drain current, W Substitute 80 for 80 for -0.6 V V for and -0.4 V for 80 2 W L 2= 2= W L (0.04) W Solve for the value of L W 2 L 0.04 200 4 50 1 Therefore, the ratio of the width to length W should 50 be L 1
