因为这些晶体管的基极注入电流(npn)或栅极加上高电平(nmos), 晶体管就会饱和, 所以这些基极或栅极对这个结点(线)的关系是或非 nor 逻辑。 如果这个结点后面加一个反相器, 就是或 or 逻辑。 注:个人理解:线与,接上拉电阻至电源。(~a)&(~b)=~(a+b),由公式较容易理解线与此概念的由来; 如果用下拉电阻...
Matsusada Precision power supply support FAQ | The open-collector output of a power supply is a method of control circuitry used to output the state (status) and other information of the power supply.
The main differences when comparing NPN transistors vs PNP transistors have been summarized in the table below:
The collector of an NPN transistor is made positive with respect to the emitter or negative for a PNP transistor.The light enters the base region where it causes hole electron pairs to be generated. This generation mainly occurs in the reverse biased base-collector junction. The hole-electron ...
The emitter-base reverse breakdown voltage of the lateral PNP is on the order of 18 V. Much higher than the 2 to 7 V of the vertical NPN transistors. 31 Here are some general guidelines about the presence, or non-presence, of input clamps relativ...
PNP and NPN are the two distinct kinds of transistors, and each has a different circuit symbol. Each of both transistors, which are built of semiconductor materials, has a unique set of layers. NPN silicon transistors, which are the simplest to produce, are the most widely used transistors....
Each electrolysis cell includes multiple identical NPN and the PNP transistor which are located on the edge strip of the capacitor which is laid out on the median. Each transistor, two emitters, has the base, and the collector. The open field area is guaranteed on the silicon substrate of ...
What is the main parameter for characterizing NPN or PNP bipolar transistors? Explain the working of nor gate using a transistor. How is it possible to change CPU clock speed,if we know that CPU is printed and electricity speed can't change,I mean what physically happens?
What is NPN and PNP transistor? NPN and PNP refer tothe arrangement of the pieces that make up the transister. ... An NPN transistor has a piece of P-type silicon (the base) sandwiched between two pieces of N-type (the collector and emitter). In a PNP transistor, the type of the ...
Output or collector characteristics : This is a set of curves of collector current IC against collector-to-emitter voltage VCE for different constant base currents IB, as shown below. (a) For VBE less than the threshold voltage for the junction, IB=0 and IC=0 i.e., there is no curren...
