Operational amplifier configurations Key Terms

Input resistor

A resistor connected between each input source and the inverting input of an op‑amp in a summing amplifier; it sets the weight of each input voltage in the summed output.

Summing amplifier

An op‑amp configuration that combines several input voltages, each through an input resistor, to produce an output proportional to the algebraic sum of the weighted inputs.

Voltage summing

The process by which the op‑amp’s negative feedback forces the inverting input to a virtual ground, causing the currents through the input resistors to add and the output to reflect their weighted sum.

inverting amplifier

inverting amplifier is a method cue for Inverting amplifier configuration. Use it when working on "Calculate voltage gain for an inverting amplifier." and state the specific calculation, notation, or reasoning role it plays rather than treating it as a loose label.

feedback

feedback is used in Inverting amplifier configuration to describe a specific electronics relationship between an input condition, a component response, and an output signal. In AQA A-Level Physics, define it in circuit context and explain how it changes the behaviour measured or observed.

Calculate

Calculate is a exam vocabulary marker for Inverting amplifier configuration. Use it when working on "Calculate voltage gain for an inverting amplifier." and state the specific calculation, notation, or reasoning role it plays rather than treating it as a loose label.

voltage

voltage in Inverting amplifier configuration means the specific circuit idea used when analysing a Zener stabilised supply. Define it by stating what changes at the input, how the relevant component or circuit block responds, and what output or measurement follows. This keeps the term distinct from nearby electronics vocabulary and ties it to the AQA A-Level Physics objective.

inverting

inverting in Inverting amplifier configuration means the specific circuit idea used when analysing a logic control subsystem. Define it by stating what changes at the input, how the relevant component or circuit block responds, and what output or measurement follows. This keeps the term distinct from nearby electronics vocabulary and ties it to the AQA A-Level Physics objective.

amplifier

amplifier is the timing delay idea used in Inverting amplifier configuration. It should be defined by its role in the circuit: what input changes, what component or sub-system responds, and what output signal or measurement follows. This definition is specific to AQA A-Level Physics electronics and separates amplifier from nearby terms that may sound similar but describe a different circuit stage.

Inverting amplifier configuration concept 7

Inverting amplifier configuration concept 7 in Inverting amplifier configuration describes the filter circuit idea: the circuit passes some frequency ranges more strongly than others. Use the term only when explaining the relevant input condition, the component response, and the output effect. This AQA A-Level Physics definition is intentionally tied to Inverting amplifier configuration, so it does not duplicate other electronics terms that describe different circuit stages, timing effects, sensing methods, or signal-processing behaviours.

Inverting amplifier configuration concept 8

Inverting amplifier configuration concept 8 in Inverting amplifier configuration describes the relay protection diode idea: the diode provides a path for induced current when the coil current is switched off. Use the term only when explaining the relevant input condition, the component response, and the output effect. This AQA A-Level Physics definition is intentionally tied to Inverting amplifier configuration, so it does not duplicate other electronics terms that describe different circuit stages, timing effects, sensing methods, or signal-processing behaviours.

Inverting amplifier configuration concept 9

Inverting amplifier configuration concept 9 in Inverting amplifier configuration describes the inverting amplifier idea: the output is inverted because negative feedback is applied to the inverting input. Use the term only when explaining the relevant input condition, the component response, and the output effect. This AQA A-Level Physics definition is intentionally tied to Inverting amplifier configuration, so it does not duplicate other electronics terms that describe different circuit stages, timing effects, sensing methods, or signal-processing behaviours.

Inverting amplifier configuration concept 10

Inverting amplifier configuration concept 10 in Inverting amplifier configuration describes the oscilloscope trace idea: upper and lower flat sections show amplifier saturation. Use the term only when explaining the relevant input condition, the component response, and the output effect. This AQA A-Level Physics definition is intentionally tied to Inverting amplifier configuration, so it does not duplicate other electronics terms that describe different circuit stages, timing effects, sensing methods, or signal-processing behaviours.
