98 results about "Differential amplifier" patented technology

A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. It is an analog circuit with two inputs Vᵢₙ⁻ and Vᵢₙ⁺ and one output Vₒᵤₜ in which the output is ideally proportional to the difference between the two voltages Vₒᵤₜ=A(Vᵢₙ⁺-Vᵢₙ⁻) where A is the gain of the amplifier.
