  1. TUGAS PRESENTASI DASAR ELEKTRONIKA KELOMPOK : FUAD ILHAM SUBIC JATI UTOMO AFANDY AMIR ZULASR

  2. EKUIVALEN AC TRANSISTOR PENGERTIAN RANGKAIAN KESIMPULAN

  3. PENGERTIAN AnalisisAC adalahanalisapenguatsinyalkecil, denganmembloksinyal DC yaitudenganmemberikankapasitorCouplingpadasinyal input dansinyal output. Untukanalisis AC semuakapasitor coupling dan bypass dianggapsebagaihubung-singkat, sehinggasemuasumberteganganpada DC dianggap seolah-olahterhubungdengan ground.

  4. PENGERTIAN BYPASS COUPLING

  5. RANGKAIAN DASAR EKIVALEN AC • Model π Saatsinyal input AC dihubungkandenganpenguat transistor, adategangan basis-emiter AC Vbepada diode emitter. Menghasilkanarus AC ib Sumbertegangan AC harusmensuplayarus basis AC ini, sehinggapenguat transistor bekerjadenganbaik.

  6. RANGKAIAN DASAR EKIVALEN AC • model Ebers-Moll Model AC yang pertama kali adalah model Ebers-Moll yang berbentuksepertihuruf T. Rangkaianinimenggunakansinyal AC yang kecil. Dan menggunakandiode emitter sebagairesistansir’edan diode colectorsebagaisumberarusic.

  7. PERBANDINGAN RANGKAIAN EKIVALEN AC & DC

  8. Perhitungan Vin = ib ( rE + r’e ) Zin(basis) =  ( rE + r’e ) Vo = - ibrLZin = R1 // R2 //  ( rE + r’e )Zo= RC

  9. Vo = ie.rL Vin = ib..r’e + ie.rL Vin = ie.r’e + ie.rL Vin = ie.( r’e + rL)
