self-bias

self-bias

[¦self ¦bi·əs]
(electronics)
A grid bias provided automatically by the resistor in the cathode or grid circuit of an electron tube; the resulting voltage drop across the resistor serves as the grid bias. Also known as automatic C bias; automatic grid bias.

This shows a self-bias, because only 50% of drivers can really be above average.
However, they are too lossy to be used at frequencies > 600MHz under self-bias condition, i.
The method comprises the steps of placing the sector on an electrode table in a cleaning tank with the molding surface of the sector facing a discharge electrode, supplying the reaction gas to the cleaning tank while pressure in the cleaning tank is reduced, supplying a high-frequency power to the discharge electrode to create the plasma between the discharge electrode and the molding surface of the sector, and applying to the electrode table a high-frequency voltage having a frequency lower than a high frequency wave supplied to the discharge elctrode to make the electrode table generate a negative self-bias.
Personal experiences seldom give us a full picture, and most of us are not aware of our limitations and self-bias.
The bias current is regulated to within two percent over a -40[degrees] to +85[degrees]C ambient temperature and maintains good supply insensitivity similar to the conventional resistive self-bias Darlington gain blocks that operate from the higher 8 V supply.
The company is also applying this innovative Darlington self-bias technique to microwave frequency gain blocks up to 20 GHz as well as lower 3 to 3.
The self-bias between the plasma and the substrate can be optionally modulated by applying the independent AC bias power to the substrate.
The TGA2512 wideband LNA is appropriate for applications where high gain is required and self-bias is desired.
