WebSep 26, 2024 · The reason some suggest not to use low Ic/Ib ratios (i.e. they warn you against putting the BJT in deep saturation) is because the deeper the saturation, the larger the stored charge in the base, the longer the turn-off time (like a diode). That's why TTL … WebBecause a sudden voltage change on one plate of a capacitor causes the other plate to change by a similar amount, this sudden rise at TR1 collector is transmitted via C1 to TR2 …
