Exam 35: Operational Amplifiers

The dc current through the emitter resistor is often called the ______________ current.

It is most common to specify the CMRR in ______________.

Which of the following is not another name for op amp voltage follower?

An op amp that uses JFETs in the input differential amp and bipolar transistors for the following stages is called a bi-FET op amp.

Bi-FET op amps generally have a wider bandwidth, higher slew rate, larger power output, higher input impedances, and much lower input bias currents.

Because the stages inside of an op amp are direct coupled,

Operational amplifiers are linear ICs that can be used to amplify signal frequencies that extend from 0 Hz to well above 1 MHz.

The open-loop voltage gain of an op amp is the ratio of its output voltage to its differential input voltage.

With the instrumentation amplifier shown in Figure 33-19, A₁ and A₂ are in what op amp configuration?
