EECS 16B: Designing Information Devices & Systems II - Operational Amplifiers

Vocabulary flashcards based on concepts discussed in the lecture for EECS 16B, focusing on operational amplifiers and their applications.

Operational Amplifier

An electronic component capable of amplifying voltage signals and performing mathematical operations such as addition and subtraction.

Inverting Amplifier

An amplifier configuration where the output is inverted and the gain is determined by the ratio of feedback and input resistors.

Non-inverting Amplifier

An amplifier configuration that outputs a signal in phase with the input, providing amplification without inversion.

Unity Gain Buffer

An amplifier setting which produces an output that maintains the same voltage as the input voltage, often used to prevent loading effects.

Gain

The ratio of the output voltage to the input voltage in an amplifier, often expressed in decibels (dB).

Slew Rate

The maximum rate of change of output voltage of an operational amplifier, related to the frequency and amplitude limitations.

Differential-mode Signal

The component of a signal that represents the difference between two signal inputs, useful in instrumentation amplifiers.

Common-mode Noise

Interference that appears equally on both the signal and ground lines, which can degrade the quality of the desired signal.

Instrumentation Amplifier

An amplifier designed to amplify small differential signals while rejecting common-mode noise, typically used with transducers.

Feedback Configuration

The method of connecting output back to input in amplifiers that enhances stability and accuracy of the circuit.

Arithmetic Functions

Basic operations like addition and subtraction performed by operational amplifiers on voltage signals.
