Analog sxemalarida kuchaytiruvchi element sifatida ishlovchi bipolyar tranzistorning asosiy parametrlari boβlib ΠΠ ning re va ΠΠ rk differensial qarshiliklari va mos ravishda Ub hamda Ue ulangan sxemalarda esa h21b va h21e differensial tok uatish koeffitsientlari xizmat qiladi. Tranzistor chastota xususiyatlari parametrlarining chastotaga bogβliqligi bilan ifodalanadi.Tok uzatish differensial koeffitsientining chegaraviy chastotasi f=fcheg transistor sifatini belgilovchi eng muhim koβrsatkich hisoblanadi.
