9.68 When the output of a BJT differential amplifier is taken differentially, its CMRR is found to be 34 dB higher than when the output is taken single-endedly. If the only source of common-mode gain when the output is taken differentially is the mismatch in collector resistances, what must this mismatch be (in percent)?
