  • Developing Article Negative feedback amplifier: An amplifier in which a fraction of its output is combined with the signal at its input that opposes the signal in what is called negative feedback in order to improve performance and to reduce sensitivity to parameter variations introduced by manufacturing or environmental uncertainties. [e]
  • Developing Article Nullor: A theoretical network element with infinite gain useful for modeling circuits containing operational amplifiers [e]
  • Developed Article Operational amplifier: A DC-coupled high-gain electronic voltage amplifier with differential inputs and, usually, a single output. [e]
  • Common-base amplifier: A single bipolar transistor amplifier with grounded base, signal applied to the emitter and output taken from the collector. The input and output signals may be currents or voltages. [e]
