Utilizing ∆Vbe sensing to get accurate and calibration-free measurement of the transistor’s absolute (Kelvin) temperature, thereby facilitating an accurate temperature setpoint [1]. An obvious ...

Your circuit creates the current ratio based on a resistor drop between the supply and Vbe of Q2. As temperature changes, Q2’s Vbe changes (the whole point of the exercise). But, there is the Early ...

There are numerous differences between NPN and PNP transistors, and even though both are bipolar junction transistors, the direction of current flow is the name of the game.

2nd Edition, p. 64: “Transistor man”. I’m not embarrased to admit that I checked while editing the article.

If you are driving the transistor’s base with 0V to 5V while emitter is on 12V (Vbe is then -7V to -12V), you can’t fully turn the transistor off as there is some base current flowing at all ...

An NPN transistor has three legs. In circuit diagrams or symbols, the legs of an NPN transistor can be identified as follows: Base (B) : Usually located in the middle.

Zetex Semiconductors has introduced a series of miniature NPN and PNP transistors for MOSFET gate driving in latest generation power supplies. ZXTN and ZXTP transistors The first bipolars to be ...

Delta V BE ( V BE)-based thermometry is based on the “PTAT V BE effect,” which says that for an ideal transistor, the V BE corresponding to changes in collector current is exactly proportional ...
