What are sleep transistors?

A rest transistor is either a pMOS or nMOS high VT transistor and is utilized as a change to close off force supplies to parts of a configuration in standby mode. The pMOS rest transistor is utilized to switch VDD supply and henceforth is known as a "header switch."

Is a parameter a measurable characteristic of a sample?

this is false... a parameter is a measure of a mean or mode, a measurable characteristic of a sample is called a statistic.

Current flow in transistor?

A; Must define the transistor type and its mode of application if you expect an answer. It has the capabilities to conduct both way on either type dueing saturation mode. Hope that helps


What is Sink and source mode of transistor?

Source mode at output provides safety than sink at output


When can there be no mode?

A mode is the number that appears most frequently in data. For instance, in the set 2,3,3,5,7,7,7,7,8,9,9 the mode is 7. Something is bimodal if two numbers have the equally high frequency. Data is trimodal if there are three equally frequent numbers, and so on. If all numbers occur at equal frequency, for instance in the set 2,2,4,4,5,5,7,7,8,8,9,9, then there is no mode.


What is the difference between a transistor used as a switch and an amplifier?

A transistor used as a switch is operated in saturated mode, where the ratio of base-emitter current over collector-emitter current is far more than hFe, or beta gain. The transistor is either fully on or fully off in this mode. A transistor used as an amplifier is operated in linear mode, where the ratio of base-emitter current over collector-emitter current is equal to or less than hFe, or beta gain. The transistor is partially on in this mode, and is operating as a current controlled current sink.
