Welcome to your Op-Amps and Circuits
The operation of a logarithmic amplifier is based on
In the differential mode of an op-amp,
Which of the following characteristics does not necessarily apply to an op-amp?
If the voltage gain for each input of a summing amplifier with a 4.7 kΩ feedback resistor is unity, the input resistor must have a value of
If a certain op-amp has a midrange open-loop gain of 200,000 and a unity gain frequency of 5 MHz, the gain-bandwidth product is
Common-mode gain of an op-amp is
When an op-amp is operated in the single-ended mode, the output is grounded
For an op-amp with negative feedback, the output is
Of the valued listed, the most realistic value for open-loop gain of an op-amp is
Typically, an instrumentation amplifier has an external resistor used for
In an op-amp, the purpose of offset nulling is to
When you apply a triangular waveform to the input of a differentiator, the output is
To make a basic instrumentation amplifier, it takes
An Op-amp in the common mode has
In a differentiator, the feedback element is
A certain inverting amplifier has an Ri of 0.1 kΩ and an Rf of 100 kΩ. The closed loop gain is
With zero volts on both inputs, an op-amp ideally should have an output equal to
A certain inverting amplifier has a closed-loop gain of 25. The op-amp has an open-loop gain of 100,000. if another op-amp with an open loop gain of 200,000 is substituted in the configuration, the closed-loop gain
In a zero-level detector, the output changes state when the input
When negative feedback is used, the gain-bandwidth product of an op-amp
