a transistor transforms a small inputcurrentinto a bigger output current. As a switch, it can be in one of two distinct states -- on or off -- to control the flow of electronic signals through an electrical circuit or electronic device. ...
Zooming in on the [Pulldown] data, it resembles the I-V characteristic curve of a MOSFET as shown in Figure 11.Figure 11. An ADxxxx DOUT1 pulldown plot (zoomed view).In saving the pulldown data, take note that it constitutes to the total current from [GND_Cl...
This resistor should be dimensioned according to the ‘collector’ load ( an LED in this case ), for a correct operation of the circuit, ( the formula can be obtained from one of my previous articles,’…safe current through LEDs…’). If a PNP transistor is used for the above experimen...
Atransistorworks by controlling the flow of current through a semiconductor material. The current is controlled by the voltage applied to the transistor’s base.Transistorscan be used as switches or amplifiers. When used as a switch, the transistor can be turned on or off, depending on the vol...

They're illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor. The life span of an LED surpasses the short life of an incandescent bulb by thousands of hours. Because of these advantages, tiny LEDs are one of the ...
Die size has a direct impact on the power and performance trade-off in processors. Smaller die sizes generally result in lower power consumption due to reduced distances between transistors and improved thermal management. However, smaller dies may have limitations in terms of transistor count and ...
Therefore you need to add a transistor to amplify the current that flows through the CdS cell. A typical circuit might look like this: Base Emitter Collector If a small amount of current flows from emitter to base, then a large amount of current can flow from emitter to collector. In ...
While ideally the RDS(ON) value should be zero for a MOSFET when fully on, it is generally in the range of a few ohms due to its physical structure. This takes into account the total series resistance in the current flow path from drain to source. RDS(ON) is the true basis for ...
Lee Ritchey, a pioneer in high-speed boards who designed a radio for the Apollo program at NASA right out of college (seven of those radios may still be on the moon right now) and put the very first transistor on the moon, aptly advises new designers, ...
