Your task is to design the three resistor values of R1, R2, and RE, and verify that they will meet the requirements described below. Select your resistor values from standard 5% ¼W resistors using the following table:

Q1 (2N3904) has VBE = 0.75 V, VA = 50 V and = 250. VCC = 2.5V is provided by 2xAA batteries and rated at 2000mAh capacity. The coupling and bypass capacitors are large enough to be treated as AC short-circuits. The LT1880 output can be represented as a Thévenin-equivalent source with vI = 400mVpk, RI = 0 .

Give all other answers correct to 3 significant figures. Make sure to maintain the following standard notation for both current and voltage: iE (ac + DC) = ie (ac) + IE (DC) vE (ac + DC) = ve (ac) + VE (DC) (a) Ensure that

Q2 will remain in the forward-active region throughout its AC swing of 400mVpk. Do not let the dynamic current iE drop below zero, hence setting IE > 25mA. (b) Ensure that the small-signal gain AVT = VO/vB will be > 0.95
