operating point

The operating point is a circuit-determined voltage- current value for an electronic component that has been specified for an electronic circuit.

The voltage-current value is determined by the circuit dimensioning of the components and the working resistance, which directly influence the transmission and amplification behavior of the circuit. The operating point is the static point within a set of characteristics at which no input signal is present.

Operating point in a transistor characteristic array

The operating point is located in the characteristic field of transistors and diodes and plays an important role in the development of an electronic circuit, since the circuit functions are significantly determined by it, such as the gain and distortion caused by the circuit, the mixing behavior and the propagation times, and some more.

The slope of the operating characteristic curve running through the operating point is determined by the operating resistance. The operating characteristic determines the dynamic range of the electronic circuit.
