| PCB CFA BJT OITPC V01 |
PCB Amplifier ANDA PA CFA BJT OITPC V01 ini merupakan versi komersial
(bukan yang free) pengembangan dari simple CFA BJT. Menerapkan topologi
CFA (Current Feedback Amplifier) dengan kompensasi OITPC (Output
Inclusive Two Pole Compensation).
Transistor final menggunakan 2 pasang BJT dengan configurasi TEF (Triple Emitter Follower) sehingga mampu dibebani hingga 2 ohm.
Transistor input stage Q3, Q4, Q8, Q9 sebaiknya matching untuk meminimalkan distorsi. Bias disetting sebesar 150mA (tegangan jepit R_emitor transistor final R65, R66, R68, R69, R72, R73, R74, R75 sebesar 35mV) dengan mengatur trimpot R39. Q15, Q20, Q21, Q22, Q23, Q24, Q25 dipasang pada satu pendingin.
Hasil Simulasi :
PM 73 GM 22
34W/8Ohm, 1kHz -> 0.000102%
34W/8Ohm, 20kHz -> 0.000182%
SR 622
PSRR 1kHz -> 137
