Select the order in which the frequency should be maintained to enhance the stability of differentiator? Where fa -> Frequency at which gain =0 ; fb -> Gain limit frequency ; fc -> Unity gain bandwidth.

Correct Answer: fa b c
The value of internal resistor and capacitor and feedback resistor and capacitor of the differentiator values should be selected such that fa b c to make the circuit more stable.

If fp is the bandwidth of the differentiator, then the desired frequency characteristic should be linear in the range of _____________

An internally compensated op amp is specified to have an open-loop dc gain of 106 dB and a unity gain bandwidth of 3 MHz. Find fb and the open-loop gain at fb.

Consider the following statements with respect to the feedback of the control systems. i. Feedback can improve stability or be harmful to stability if it is not properly applied. ii. Feedback can always improve stability iii. In many situations the feedback can reduce the effect of noise and disturbance on system performance. iv. In general the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located.

A particular op amp, characterized by a gain–bandwidth product of 20 MHz, is operated with a closed-loop gain of +100 V/V. What 3-dB bandwidth results? At what frequency does the closed-loop amplifier exhibit a −6° phase shift?

An inverting amplifier with nominal gain of −20 V/V employs an op amp having a dc gain of 104 and a unity-gain frequency of 106 Hz. What is the 3-dB frequency f3dB of the closed-loop amplifier?

Two non-inverting amplifiers, with gain =1 and gain=20 are made using identical operational amplifiers. As compared to the unity gain amplifier, the amplifier with gain=20 has ___________

Workstations connected to a port on a modern lOBase-T Ethernet HUB all use the same bandwidth, i.e. the bandwidth is shared across all available ports, the less ports, the less bandwidth available per port
