13 Define the terms a. common-mode voltage b. common-mode gain c. CNRR What is a typical value for the CMRR of an op-amp? Figure P2.13 shows differential amplifier circuit with a flying capacitor. The switch pairs \( \mathrm{A} \) and \( \mathrm{B} \) turned on and off alternately during operation. For example, first the switc denoted by \( \mathrm{A} \) are turned on (closed) with the switches B off (open). Next, switches \( \mathrm{A} \) are opened and the switches \( \mathrm{B} \) are closed. Explain why this arra ment provides good common-mode rejection characteristics.
