Önemli Kurallar/Important Rules:

Sınavlarda hesapladığınız akım ve gerilimlerin yönlerini çözüm kağıdı üzerinde belirtiniz. Kağıdınızı okuyan kişi sınav sırasında aklınızdan geçen herşeyi kestirebilecek güçte olmadığı için, anlayamadığı hesaplara not veremez.

Hesap yaparken birim uyumuna dikkat ediniz ve sonuçları yazarken birimleri unutmayınız.

Please indicate all current directions and voltage polarities on your solution sheets. No one can evaluate what went in your brain without any hint! Thus you may not get any points for solutions with missing steps in calculations.

Be aware of all the UNITS and do not mix them. Also always indicate the units in your solution. You will be penalized for missing units.

Yarıyıl içi ve yarıyıl sonu sınavlarında her öğrencinin A4 boyutlu bir "kopya kağıdı" kullanma hakkı vardır. Arkalı önlü olarak hazırlanabilecek olan bu kağıda öğrenci sınav için gerekli olduğuna inandığı herşeyi yazmakta serbesttir; ANCAK, "kopya kağıdı" bilgisayar çıktısı veya fotokopi yöntemi ile çoğaltılamaz, her öğrenci kendi "kopya kağıdı"nı kendi el yazısı ile hazırlar. Sınav sonunda kağıtlar toplanırken "kopya kağıt"ları da sınav kağıtları ile beraber toplanır. Yararlanıldığı halde "kopya kağıdı" olmayan sınav kağıdının puanı düşürülecektir.

Benzer biçimde, sınav sırasında ders notları, defter veya çözümlü problemler kullanılmaz; böyle bir girişimde bulunan öğrencinin sınav kağıdının puanı düşürülecektir.

Sınavlara gerçek hesap makinesi ile geliniz, her ne için olursa olsun cep telefonlarını kullanmanıza izin verilmeyecek, cep telefonları sınav sırasında kapalı kapalı tutulacak ve ASLA kullanılmayacaktır. Kullanma girişiminde bulunanlar cezalandırılacaktır.

During midterm and final exams each student may bring and use an A4 size "copy sheet". This double sided hand prepared copy sheet may contain all formulae the student thinks is important for solving exam problems. HOWEVER, the "copy sheet" MAY NOT be a printout or photocopy of someone else's. At the end of the exam period the copy sheet should be turned in along with problem solutions.

No class notes or problem solutions may be used during the exam; anyone attempting to use such material will be penalized.

You may only use a real calculator during the exam, cell phones are not allowed, and should be turned off. Anyone attempting to use his/her cellphone(s) will be strictly penalized.

Textbooks:

"Microelectronic Circuits International edition," International ed. Adel S. Sedra and Kenneth C. Smith, 2010, ISBN: 978-0199738519.

"Electronic Devices and Circuit Theory," 11th ed, Robert L. Boylestad and Louis Nashelsky, 2012, ISBN: 978-0132622264.

Unfortunately, Semiconductor Electronics is not well covered in both of these books above. Thus

Elektronik Elemanları, Duran LEBLEBİCİ, VOLGA YAYINCILIK, 2016.

Elektronik Devre Elemanları, Avni MORGÜL, PapatyaBilim, 2016.

Çözümlü Elektronik Devreler, Mehmet Sait Türköz, BİRSEN YAYINEVİ.

are recommended.

Have a look at online library resources such as CRC ENGnetBASE.
