Question 2 RD Oxford Microelectronic Circuits by Adel S. Sedra and Kenneth C Smith (0195323033) Gnd What is the voltage at the gate (VG)? Give your answer in number form to 2 decimal places, no units, no unit prefixes, no decimals, no commas Example: 5V>Answer Given: 5.00]

Answer 1

Given that current into gate terminal at MOS transistor is negligible therefore I_4 = 0 V_G = VDD times R_G2/R_G1 + R_G2 (By voltage Division rule) V_G = VDD times R_G2/2 R_G2 + R_G2 (Given R_G1 = 2R_G2) V_G = VDD R_G2/3R_G2 V_G = VDD/3 since VDD = 3 V_G = 3/3 V_G = 1V
