EEE :: OP amp
- An amplifier using an opamp with slew rate SR=1v/sec has a gain of 40db.If this amplifier has to faithfully amplify sinusoidal signals from dc to 20KHz without introducing any slew-rate induced distortion, then the input signal level exceed
- Current cannot flow to ground through .
- When a step-input is given to an OP-amp integrator, the output will be
-
An OPAMP has a slew rate of 5 V/μ S .The largest sine wave O/P voltage possible at a frequency of 1 MHZ is
[Hint: Slew rate is defined as the max. rate of change of output voltage. Its unit is V/μS.] - Calculate the cutoff frequency of a first-order low-pass filter for R1 = 2.5kΩ and C1 = 0.05μF
- The output of a particular OP-amp increases 8V in 12µs. The slew rate is
- The approximate input impedance of the opamp circuit which has Ri=10k, Rf=100k, RL=10k
- For an OP-amp with negative feedback, the output is .
- The common mode voltage gain of a differential amplifier is equal to RC divided by
