What is the difference between common-mode and differential-mode input signals?
Current actually flows into or out of a virtual ground.
The feedback resistor adds to the gain of an op-amp.
A noninverting closed-loop op-amp circuit generally has a gain factor:
How many logic states does an S-R flip-flop have?
What starts a free-running multivibrator?
If the frequency of an astable multivibrator is 54.86 kHz then its period is 1.82 s.
The Schmitt trigger is a two-state device that is used for:
Another name for a unity gain amplifier is:
A circuit that uses an amplifier with passive filter elements is called a(n):
A voltage-follower op-amp has the output connected directly to the inverting input.
The frequency of a crystal is dependent on how much voltage is applied to activate it.
A 555 timer can be configured as an astable multivibrator.
In order for an output to swing above and below a zero reference, the op-amp circuit requires:
An output that is proportional to the addition of two or more inputs is from which type of amplifier?
In a PLL, to obtain lock, the signal frequency must:
A portion of the output that provides circuit stabilization is considered to be:
An open feedback resistor in an inverting or noninverting op-amp circuit can cause severe clipping of the output signal.
Feedback is used in an open-loop operational amplifier circuit.
When a capacitor is used in place of a resistor in an op-amp network, its placement determines:
An operational amplifier contains a differential amplifier, a voltage amplifier, and an output amplifier.
The open-loop voltage gain (Aol) of an op-amp is the
A virtual ground is a ground for current, but not for voltage.
The input offset current equals the
If the two inputs to a differential amplifier are exactly the same, then the output is the signal multiplied by 2.
A monostable multivibrator must be triggered.
The voltage-follower amplifier circuit has a fixed voltage gain of approximately 10.
Crystal oscillator circuits have a very low Q.
Op-amps used as high- and low-pass filter circuits employ which configuration?
An ideal amplifier should have:
