A differential amplifier is characterized by the first equation in Problem 2.60 on page 118 of the Text where CMRR is also defined. It is found to have a difference-mode gain of 200VN and a CMRR of 100dB. For what amplitude of input common-mode signal is the unwanted output signal only 1% of the desired difference-mode output of 2Vpp?
arrunesInsa 2.41 An internally-compensated op amp has f, of 10 MHz and a dc gain of 106 VN. What is the 3 dl) frequency of its open-loop gain? If this amplifier is to be operated at 100 kHz, what open-loop gain is available?
