Definition of grid bias in English: grid biasnoun Electronics A fixed voltage applied between the cathode and the control grid of a thermionic valve which determines its operating conditions. Example sentencesExamples - The plate power supply, the screen grid power supply, and the control grid bias supply are connected in series.
- The actual signal that drives the tube is the combination of the grid bias and the audio drive signal.
- Furthermore, there is a frame containing three rectifiers for the grid biases of different stages.
- One solution is to provide some negative grid bias to reduce the screen sensitivity.
- This form of grid bias is suitable only for small a valves having very small signal input voltages.
