A common-source amplifiers utilizes a MOSFET operated at VOV = 0.1 V. The amplifier feeds a load resistance RL = 30 kΩ. The designer selects RD = 20 kΩ. If it is required to realize an overall voltage gain Gv of −12 V/V, what bias current ID is needed? Express your answer in mA. Type in the value of ID without the unit (mA).
