pass element

pass element

[′pas ‚el·ə·mənt]
(electronics)
Controlled variable resistance device, either a vacuum tube or power transistor, in series with the source of direct-current power; the pass element is driven by the amplified error signal to increase its resistance when the output needs to be lowered or to decrease its resistance when the output must be raised.

The consultation also swaps the bus pass element for a one-off PS150 cash payment.
In addition, the clamp's use of a very low resistance p-channel MOSFET as the pass element ensures that any EMI issues are removed.
"So is it fair that one person has to pay and another doesn't?" The bus pass element of the school transport budget was overspent in 2010/11 by pounds 32,000, and long term demand is expected to rise.
She will examine the proposals drawn up by council benefits and admissions manager Sue Heawood, who states: "The bus pass element of the school transport budget was overspent in 2009/10 by pounds 91,000," adding, "While some of this overspend will be reduced in 2010/11 through savings...
Some LDOs have better performance in certain categories than others based on the type of pass element employed.
Most LDO regulators use an N- or P-channel FET pass element and can offer a dropout voltage of 100 mV or less.
One of the first approaches in integrating fault protection with an analog switch was for a certain type of multiplexer whose pass element consists of three MOSFETs in series (n-channel/p-channel/n-channel).
The power losses can be approximated by the product of input to output voltage difference times the current flowing through the linear pass element.
"To create more jobs in particularly hard-hit sectors, President Obama continues to urge Congress to pass elements of the American Jobs Act, including further investment in infrastructure to rebuild our Nation's ports, roads and highways, and assistance to State and local governments to prevent layoffs and to enable them to rehire hundreds of thousands of teachers and first responders", he added.
If not, he said, it becomes more critical for the Legislature to pass elements of the governor's municipal partnership act, aimed at giving cities and towns new ways to cut costs.
