Bias Calculator


In order to optimize the working point of electronic devices or circuits, bias refers to the application of a constant voltage or current.
By ensuring that the apparatus functions within its linear or active domain, it facilitates appropriate signal processing, modulation, or amplification.

The main objective of biasing electronic components is to provide signal processing with a steady and reliable working point.
It keeps electronics from working in unfavorable areas, such cutoff or saturation, which could cause distortion or ineffective operation.

This digital instrument is designed to calculate a tube amplifier’s bias in milliamperes (mA) or amperes (A). The high-frequency alternating current used in tape recorders to lessen distortion is referred to as bias. Bias determines the ideal current flow through the tube in tube amplifiers that are not in use. This bias calculator makes it possible to determine the current by giving information about the amplifier, including its class type, plate dissipation, tube type, and plate voltage.
