  • सामान्य-संकलक संरुपण , ज्याला एमिटर फॉलोअर असेही म्हणतात, उच्च इनपुट प्रतिबाधा आणि कमी आउटपुट प्रतिबाधा प्रदान करते. म्हणून ते प्रतिबाधा जुळणीच्या उद्देशाने वापरले जातात.
  • सामान्य-संकलक संरुपणमध्ये, कलेक्टर टर्मिनल निवेद आणि उत्पाद टर्मिनल्स दोन्हीसाठी सामान्य आहे.

 

त्यामुळे DC प्रवाह गेन बेस करंटच्या एमिटर करंटच्या गुणोत्तराने दिला जातो, म्हणजे.

\(\gamma=\frac{I_E}{I_B}\)

IE = एमिटर प्रवाह

IB = बेस प्रवाह

तसेच, IE = IB + IC

DC प्रवाह लाभ असेल:

\(\gamma=\frac{I_C+I_B}{I_B}=\frac{I_C}{I_B}+1\)   ---(1)

सामान्य एमिटर कॉन्फिगरेशनसाठी डीसी वर्तमान लाभ खालीलप्रमाणे परिभाषित केला आहे:

\(\beta=\frac{I_C}{I_B}\)

समीकरण (1) आता बनते:

\(\gamma=\beta +1\)
