The increase in the input frequency of the differentiation amplifier to input impedance creates

The increase in the input frequency of the differentiation amplifier to input impedance creates Correct Answer High frequency noise

The input impedance of the amplifier decreases with increase in frequency and make the circuit susceptible to high frequency noise such that noise can completely over ride differential output.

Assertion: The process of testing the frequency response of amplifier and filter can be done by sweep frequency generator that automatically varies its frequency over a pre-determined range. Reason: The sweep frequency generator should have a ramp generator which applies a linear ramp voltage the input of a voltage tuned oscillator (VTO).

In designing with op amps one has to check the limitations on the voltage and frequency ranges of operation of the closed-loop amplifier, imposed by the op-amp finite bandwidth (ft), slew rate (SR), and output saturation (Vo max). Consider the use of an op amp with ftt = 2 MHz, SR = 1 V/µs, and V0 max = 10 V in the design of a non-inverting amplifier with a nominal gain of 10. Assume a sine-wave input with peak amplitude Vi. If Vi = 0.5 V, what is the maximum frequency before the output distorts?
