Problems 1 to 14 is True or False: 1. An ideal op-amp has an infinite input impedance. of 002 mol bagna - huge 2. An ideal op-amp has a very high output impedance. 3. The op-amp can operate in both the differential mode or the common mode. Vm 4. Common-mode rejection means that a signal appearing on both inputs is effectively cancelled. 5. CMRR stands for common-mode rejection reference. sanerlo son (p) 6. Slew rate determines how fast the output can change in response to a step input. 7. Negative feedback reduces the gain of an op-amp from its open-loop value. 8. Negative feedback reduces the bandwidth of an op-amp from its open-loop value. 9. A noninverting amplifier uses negative feedback. 10. The gain of a voltage-follower is very high. 11. Negative feedback affects the input and output impedances of an op-amp. ugh ni ning qool-beac 12. A compensated op-amp has a gain roll-off of above the critical frequency. 13. The gain-bandwidth product equals the unity-gain frequency. 14. If the feedback resistor in an inverting amplifier opens, the gain becomes zero. the low
