Na u batla ho tseba li-amplifiers tsa MOSFET? O sebakeng se nepahetseng. Tataiso ena e felletseng e arola ntho e 'ngoe le e 'ngoe ho tloha menahanong ea mantlha ho isa lits'ebetsong tse tsoetseng pele, e u thusa ho utloisisa mefuta e fapaneng ea li-amplifiers tsa MOSFET le ts'ebetso ea tsona e sebetsang.
Ho utloisisa lintlha tsa motheo tsa MOSFET Amplifier
Li-amplifiers tsa MOSFET li fetotse lisebelisoa tsa elektroniki tsa sejoale-joale, li fana ka ts'ebetso e phahameng haholo mabapi le ts'ebetso ea motlakase, karabelo ea khafetsa le bonolo ba potoloho. Pele re kenella mefuteng e itseng, a re utloisise hore na ke eng e etsang hore li-amplifiers tsa MOSFET li khethehe.

|---|---|---|
| Phaello ea Voltage | Holimo (180° phasefate) | Kakaretso ea morero |
| Input Impedance | Holimo Haholo | Mekhahlelo ea ho phahamisa motlakase |
| Sephetho se Impedans | E mahareng ho isa Hodimo | Mekhahlelo ea ho phahamisa motlakase |
Tloaelehileng Drain (Mohloli oa Mohloli) Amplifier
Tlhophiso e tloaelehileng ea drain, eo hape e tsejoang ka hore ke molateli oa mohloli, e nepahetse bakeng sa lits'ebetso tsa ho tsamaisana le li-buffering.
Likarolo tsa Bohlokoa:
- Keketseho ea matla a bonngoe
- Ha ho phetoho ea mekhahlelo
- Impedans e phahameng haholo
- Phokotso e tlase ea tlhahiso
Tlhophiso e tloaelehileng ea Heke Amplifier
Le ha e sa tloaeleha ho feta tlhophiso ea CS kapa CD, amplifier e tloaelehileng ea heke e fana ka melemo e ikhethang lits'ebetsong tse ikhethileng:
| Sebopeho | Boleng | Molemo |

| Input Impedance | Tlase | E nepahetse bakeng sa lisebelisoa tsa hajoale |
| Sephetho se Impedans | Phahameng | Ho itšehla thajana ho hotle |
| Karabelo ea Khafetsa | E kgabane | E loketse lits'ebetso tsa maqhubu a holimo |
Cascode Amplifier: Tlhophiso e tsoetseng pele
Amplifier ea cascode e kopanya likarolo tse ntle tsa mohloli o tloaelehileng le meralo e tloaelehileng ea liheke, e fanang ka:
- Karabelo e ntlafalitsoeng ea maqhubu
- Ho itšehla thajana ho molemo
- Miller e fokotsehile
- Phaello e phahameng ea tlhahiso
