WebLet's say you're given a circuit diagram as follows: I want to find R1 and R2 so that forward voltage drop across the LED is 2V with an overdrive factor of at least 2. Current of 25mA from a source which outputs 0 or 5V through an output resistance of 610 is given. Beta ranges from 50 - 300 So here's my approach. WebA BJT with a dc current gain of 250 is employed as a switch, with a collector current of 10 mA, in the ON state. If the overdrive factor were to be 4, then the base current should be mA This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.

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. http://www.ece.mcgill.ca/~grober4/SPICE/SPICE_Decks/1st_Edition_LTSPICE/chapter4/Chapter%204%20BJTs%20web%20version.html

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.
