Na gadi na iya kula da ingantaccen zabe ta hanyar transistor ko wasu muhimman abubuwa masu aiki a cikin zabe ta ita ce wani muhimmiyar yanayi don in fahimta aiki da kayan aiki na zabe ta. Wadannan ne wasu tarihi da kuma tattalin arziki don in gadi na ingantaccen zabe ta:
1. Tarihin Nazari
Ingantaccen Zabe ta Iko
Modeli Na Biyu: Yi amfani da modeli na biyu na transistor (kamar common-emitter, common-base, common-collector, etc.) don in tafiya ingantaccen zabe ta iko.
Amplifier Common-Emitter: Ingantaccen zabe ta Rin yana iya bayyana cewa:
ida rπ s dynamic resistance bayan base da emitter, gm shi ne transconductance,
RL shi ne load resistance, da RB shi ne base bias resistor.
Amplifier Common-Base: Ingantaccen zabe ta Rin yana iya bayyana cewa
ida re shi ne emitter resistance, da RE shi ne emitter bypass resistor.
Amplifier Common-Collector: Ingantaccen zabe ta Rin yana iya bayyana cewa
Ingantaccen Zabe ta Farko
Modeli Na Biyu: Yi amfani da modeli na biyu na transistor don in tafiya ingantaccen zabe ta farko.
Amplifier Common-Emitter: Ingantaccen zabe ta Rout yana iya bayyana cewa
ida ro shi ne output resistance, da RC shi ne collector resistor.
Amplifier Common-Base: Ingantaccen zabe ta R out an iya bayyana cewa
Amplifier Common-Collector: Ingantaccen zabe ta Rout an iya bayyana cewa:
2. Tarihin Bin Tsakawa
Ingantaccen Zabe ta Iko
Tsunfiyar Saida: Koyi AC signal na biyu a iko na zabe ta, kara tsari kan input voltage
Vin da input current Iin, da kuma kula da ingantaccen zabe ta iko:
Tsunfiyar Resistor: Series a known small resistor Rs atthe input of the circuit, measure the input voltage Vinand the voltage across the resistor Vs, and calculate the input impedance:
Ingantaccen Zabe ta Farko
Tsunfiyar Load: Hanya variable load resistor
RLat the output of the circuit, measure the output voltage Voutas the load resistance changes, and calculate the output impedance:
ida Vout,0 shi ne output voltage idan load resistance ya zama infinity.
3. Tarihin Simulation
Circuit Simulation Software: Yi amfani da software na simulation na zabe ta (kamar SPICE, LTspice, Multisim, etc.) don in simulace zabe ta da kuma samun ingantaccen zabe ta iko da farko daga baya.
Ingantaccen Zabe ta Iko: Koyi AC signal na biyu a iko na zabe ta, simula don samun input voltage da input current, da kuma kula da ingantaccen zabe ta iko.
Ingantaccen Zabe ta Farko: Hanya variable load resistor a farko na zabe ta, simula don samun output voltage idan load resistance ya zama, da kuma kula da ingantaccen zabe ta farko.
4. Tattalin Arziki na Zabe Ta
Thevenin Equivalent: Sarrafa zabe ta mai yawa zuwa Thevenin equivalent circuit, idan ingantaccen zabe ta iko shi ne equivalent resistance.
Norton Equivalent: Sarrafa zabe ta mai yawa zuwa Norton equivalent circuit, idan ingantaccen zabe ta farko shi ne equivalent resistance.
Muhimmiyar
Na gadi na iya kula da ingantaccen zabe ta hanyar transistor ko wasu muhimman abubuwa masu aiki a cikin zabe ta ita ce wani muhimmiyar yanayi don in fahimta aiki da kayan aiki na zabe ta. Zan yi amfani da tarihin nazari, tarihin bin tsakawa, da kuma tarihin simulation. Zan zaɓi tarihi a kan hukumomin da kaɗan da ake amfani da su. Tarihin nazari suna daidai don tafiya na nazari, tarihin bin tsakawa suna daidai don tafiya na tsakawa, da tarihin simulation suna daidai don tafiya na nazari da kuma tafiya na tsakawa a cikin kompyuta.
