EE2002: Your task is to design the three resistor values of R1, R2, and RE, and verify that they will meet the requirements described below: Analog Electronics Assignment, NUT, Singapore

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
