Misalai Transistor na Neman Daban-daban?

Misalai Transistor na neman daban-daban da suka taka muhimmanci a wurin transistor. Wadannan misalai, wanda maimakon hanyoyin biyu-biyu, ana bincika ta hanyar kurwurun misalai, kafin kananan:

Misalai Mawaki: Wadannan sun bayyana canza a cikin amfani a mawaki idan an yi karfi a cikin jerin shirya mawaki da ake kare a cikin tasiri.

Misalai Farko: Wani abu mai yadda ake fitar da amfani a farko daidai ga amfani a mawaki, inda jerin shirya mawaki ya zama daidai.

Misalai Amfani Daidai: Wadannan kurwurun misalai sun bayyana canza a cikin amfani a farko daidai ga amfani a mawaki, inda jerin shirya mawaki ya zama daidai.

Kudin Base (CB) na Transistor

A kudin CB, terminal base na transistor ya zama daidai a cikin terminal mawaki da terminal farko kamar yadda aka nuna a Figure 1. Kudin wannan ya ba da tsari mai yawa a mawaki, tsari mai gaba a farko, gaini mai tsari mai yawa da gaini mai shirya mai yawa.

Misalai Mawaki don Kudin CB na Transistor

Misalai Mawaki don Kudin CB: Figure 2 tana bayyana yadda amfani Emitter, IE, ya canzawa a cikin jerin shirya Base-Emitter, VBE, inda jerin shirya Collector-Base, VCB, ya zama daidai.

Wannan ya haɗa zuwa abu mai yadda ake fitar da tsari a mawaki kamar:

Misalai Farko don Kudin CB na Transistor

Misalai Farko don Kudin CB: Figure 3 tana bayyana yadda amfani Collector, IC, ya canzawa a cikin VCB, inda amfani Emitter, IE, ya zama daidai. Wannan graph ya ba da waɗanda suke kula tsari a farko.

Misalai Amfani Daidai don Kudin CB na Transistor

Misalai Amfani Daidai don Kudin CB: Figure 4 tana bayyana yadda amfani Collector, IC, ya canzawa a cikin amfani Emitter, IE, inda VCB ya zama daidai. Wannan ya haɗa zuwa gaini mai amfani mai yawa da 1, kamar yadda ake fitar da ita a karshe.

Kudin Collector (CC) na Transistor

A kudin CC, terminal collector na transistor ya zama daidai a cikin terminal mawaki da terminal farko (Figure 5) kuma ana kiran wannan da kudin emitter follower. Kudin wannan ya ba da tsari mai yawa a mawaki, tsari mai gaba a farko, gaini mai shirya mai yawa da gaini mai amfani mai yawa.

Misalai Mawaki don Kudin CC na Transistor

Misalai Mawaki don Kudin CC: Figure 6 tana bayyana yadda amfani Base, IB, ya canzawa a cikin jerin shirya Collector-Base, VCB, inda jerin shirya Collector-Emitter, VCE, ya zama daidai.

Misalai Farko don Kudin CC na Transistor

Figure 7 tana bayyana misalai farko don kudin CC, wadannan sun bayyana yadda IE ya canzawa a cikin VCE, inda IB ya zama daidai.

Misalai Amfani Daidai don Kudin CC na Transistor

Wadannan misalai na kudin CC (Figure 8) sun bayyana yadda IE ya canzawa a cikin IB, inda VCE ya zama daidai.

Kudin Emitter (CE) na Transistor

A kudin CE, terminal emitter ya zama daidai a cikin terminal mawaki da terminal farko kamar yadda aka nuna a Figure 9. Kudin wannan ya ba da tsari mai yawa, tsari mai gaba, gaini mai amfani mai yawa da gaini mai shirya mai yawa.

Misalai Mawaki don Kudin CE na Transistor

Figure 10 tana bayyana misalai mawaki don kudin CE na transistor, wadannan sun bayyana yadda IB ya canzawa a cikin VBE, inda VCE ya zama daidai.

Daga graficin Figure 10, za a iya samun tsari a mawaki na transistor kamar:

Misalai Farko don Kudin CE na Transistor

Misalai farko na kudin CE (Figure 11) suna kiran misalai Collector. Wadannan grafic sun bayyana yadda IC ya canzawa a cikin VCE, inda IB ya zama daidai. Daga graficin Figure 11, za a iya samun tsari a farko kamar:

Misalai Amfani Daidai don Kudin CE na Transistor

Wadannan misalai na kudin CE sun bayyana yadda IC ya canzawa a cikin IB, inda VCE ya zama daidai. Wannan za a iya fitar da ita a karshe kamar:

Wannan daraja suna kiran common-emitter current gain kuma yana zama da 1 kawai.

A nan, ya kamata a lura cewa al'adu da aka bayyana a cikin misalai na BJT, akwai misalai masu ilimi a cikin FET.
