Well, the gate needs a pull-down resistor to ensure transistor deactivation. This is because the gate-to-source part of a MOSFET behaves like acapacitor. So if you leave the gate floating after it has been connected to a voltage, this voltage stays at the gate and keeps the transistor on...
A word-line may be coupled to the memory cells and may have a word-line driver including a pull-up resistor coupled to the selectors for the memory cells to access respective storage elements of the memory cells. Other embodiments may be described and claimed.FABIO PELLIZZER...
R1 converts the voltage applied to the B terminal into current to stabilize the BRT operation while R2 acts as a pull-down resistor when the BRT is off, pulling the base voltage to the GND level. Without R2, the leakage current or ...

The present invention provides an asymmetric pull-down transistor in a semiconductor device. The transistor comprises a substrate, a drain region in the substrate, a source region in the substrate wherein the source region is spaced from the drain region by a channel region and extended into a ...
The N channel MOSFET gates are typically pulled low by the pulldown resistor, and the P channel MOSFET gates are pulled high. This results in both the P channel and the N channel MOSFETs are turned off; therefore, no current can flow. When the PWM signal is applied to the gates of the...
and not be left floating. One way to do this is to leave the pin unconnected and configure the pin as a general-purpose I/O input with pullup resistor. This is also the state of all pins during and after reset (except P1.0 and P1.1, which do not have pullup/pulldown capability)....
so can only pull down (sink current). When Enable is high, a low-going SCL signal drives the emitter of one of the transistors as a common-base amplifier. The 10-kΩ resistor in the base circuit provides enough current to saturate the transistor and drop the VCEvoltage to approximately ...
Up0TrueDown Ben C4 年多前in reply toMichiaki Tanii TI__Mastermind39955points Hi Michiaki, In essence, yes, you can drive the base of an NPN or PNP transistor but the speed to turn the digital transistor is affected by the value of the pull-up resistor and the si...
current. This doesn't mean you can charge it and expect the FET to continue to conduct indefinitely but it will continue to conduct until the voltage on the gate is below the threshold voltage. You can make sure it turns off if you connect a pulldown resistor between the gate and source...
