Step 1 of 3 7.020P Write the expression of voltage gain. (1) It is known that, the voltage gain A, is ratio of output voltage to input voltage. (2) Equate equations (1) and (2). (3) Step 2 of 3 Write the expression of output voltage. (Since (4) Substitute equation (4) in equation (3). = Therefore, the expression for transconductance Step 3 of 3 Determine the value of transconductance at = Substitute 0.5 mA for and 25 mV for 0.5 = 25 mV Thus, Transistor transconductance for = mA is 0.02 A/V
