This semester I take electronic subject. The book I use is MICROELECTRONICS CIRCUIT ANALYSIS AND DESIGN 3rd edition . The author is Donald A. Neamen . Among the subtopics I learned is semiconductor material, diode, transistor. All this thing I have learned when I was at the secondary school . I was in technique school in the field of mechanical engineering. Nevertheless of that, the thing I have learn in school is just the basic. In university I learn this things and discuss more deep. It involve the application . There alot of formula must be memorize .The first formula I memorize is Intrinsic Carrier Concentration that is (ni)=BT^(3/2)e^(-Eg/2KT) .
ni=Intrinsic carrier concentration
B= Coefficent related to the specific semiconductor material
T= Temperature in Kelvin
Eg= Bangap energy in unit eV
K= Boltzman constant that is 86*10^-6 (eV)
Anyway, I have exam on this subject on the day after tomorrow. So I just post a little bit about this subject to refresh what I have learn .
