WebTherefore, in order to eliminate this possibility, we use what is known as an “Overdrive Factor” (ODF). This is an arbitrary number between 2 and 10 that is used to insure that the transistor is driven hard into saturation (fully turned on) — and where temperature changes fail to drop the transistor out of saturation. Therefore, IB equals: WebApr 26, 2024 · Transistor Overdrive Factor When using a transistor as a switch the base current is defined as: Ib = Ic/B * ODF.

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. 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.
