WebDec 6, 2024 · So if you happen to select a nicely-high HFE PN2222A transistor (like HFE=200) then you only need to supply 0.1mA base current to saturate it when driving a 10mA collector or emitter load current. For such a transistor, the rule-of-thumb overdrive factor-of-10 is overkill. But woe be to you if HFE is lower, or temperature drops to -55C.

WebOct 19, 2024 · Simple BJT Overdrive. A very simple overdrive circuit is shown in Fig. 5.15. Depending on the winding resistance of the guitar pickups, this circuit provides a maximum effective gain of about 50 or so, which should be more than sufficient to overdrive any typical amplifier. The gain of the transistor may be adjusted with the 500 Ω potentiometer.

Webto forward bias the parasitic BJT, it will turn on, leading to catastrophic failure. There have been many advances in MOSFET design technology targeted at minimizing the base resistance R B to prevent the bipola r turn-on. However, no MOSFET is totally immune to latch-up. Junction temperature plays an important role in triggering the failure. http://www.ece.mcgill.ca/~grober4/SPICE/SPICE_Decks/1st_Edition_LTSPICE/chapter4/Chapter%204%20BJTs%20web%20version.html

WebThe presence of a BJT in a circuit is described to Spice through the Spice input file using an element statement beginning with the letter Q. If more than one transistor exists in a circuit, then a unique name must be attached to Q to uniquely identify each transistor.
