Consider a BJT diff-amp with the configuration in Figure P11.26. The signal sources have nonzero source resistances as shown. The transistor parameters are: β = 150, VBE(on) = 0.7 V, and VA = ∞. The range of the common-mode input voltage is to be − 3 ≤ vCM ≤ 3 V and the CMRR is to be 75 dB. (a) Design the diff-amp to produce the maximum possible differential-mode voltage gain, (b) Design the current source to produce the desired bias current and CMRR.
