2.0 prcparator_y Work 2.1 Design a Darlington pair CE amplifier to attain a voltage gain of -50 with a load of 5 kQ. Use VT 26 mV, RE = 500 0, Vic 1.4 V, Vc.c. = 10 V and a combined beta of 20,000. Use Fig 4.1. Determine R,, R2, R and max V. swing when Re
2.2 Design a single ended differential amplifier to attain a voltage gain of 50 with a load of 10 ICI. Use VT 26 mV, pe 200, Vac 0.7 V, Rif 10 kG, Vec.¦10 V, and VEs -10 V. Determine Aw(dm), A,(cm), R., and the maximum input voltage for undistorted output voltage.
2.3 Design a Darlington compound differential amplifier to attain the following specifications: Input Impedance: Z. > 800 kfa Voltage Gain: V/V.> 50 Maximum output swing for R, - 4 ka Wt. = 20 V and VEE = -20 V
(Note: The specification sheets for the transistors only gives the minimum betas for particular operating values therefore you need to check your transistors to see what betas actually exist for different current levels.) Detemine the A,(dm). AJcm), and CMRR.
2.4 For the design in 2.3 above, determine the value of Itu needed to replace the constant current source and have all the other parts remain the same as was determined in 2.3. Then calculate the differential and common mode voltage gains and the CMRR.
