"Systems on Chip (SoC) for communications, multimedia and computer applications have recently received much international attention; one such example being the single-chip transceiver. Modern microelectronic design adopts a mixed-signal approach as a complex SoC is a mixed-signal system including both analogue and digital circuits. Automatic testing becomes crucially important to drive down the overall cost of next generation SoC devices.
Test and fault diagnosis of analogue, mixed-signal and RF circuits, however, proves much more difficult than that of digital circuits due to tolerances, parasitics and nonlinearities and therefore, together with challenging tuning and calibration, remains the bottleneck for automatic SoC testing.
This book provides a comprehensive discussion of automatic testing, diagnosis and tuning of analogue, mixed-signal and RF integrated circuits, and systems in a single source. The book contains eleven chapters written by leading researchers worldwide. As well as fundamental concepts and techniques, the book reports systematically the state of the arts and future research directions of these areas. A complete range of circuit components are covered and test issues are also addressed from the SoC perspective.
An essential reference companion to researchers and engineers in mixed-signal testing, the book can also be used as a text for postgraduate and senior undergraduate students.

hingga 2500MHz. Pada penelitian ini analisa hasil pengukuran pada RPD saat
diberikan attenuator atau objek pengukuran yang berbeda diantara transmitter dan
receiver yang berbanding dengan pengukuran referensi atau hasil pengukuran
tanpa adanya objek. Rangkaian receiver terdiri atas MAX2015, ADC 16-Bit, dan
beberapa komponen pasif lainnya, dimana MAX2015 merupakan logaritmik RF
Detector yang dapat mendeteksi power pada frekuensi 0.1GHz hingga 3GHz.
Dalam penelitian ini frekuensi yang dipancarkan oleh RF Transmitter berada pada
frekuensi 2.3GHz hingga 2.5GHz, hal ini dilakukan berdasarkan referensi dari
beberapa jurnal dan penelitian yang dapat dipercaya. Dari hasil penelitian
didapatkan bahwa Antenna memiliki puncak respon maksimum pada frekuensi
2.4GHz, dimana objek yang digunakan adalah balok kayu, balok nilon, dan balok
alumunium dengan panjang 60mm, lebar 40mm, dan tinggi 80mm.

"Latar belakang: Neuropati perifer terinduksi kemoterapi (NPTK) merupakan efek samping kemoterapi neurotoksik yang menurunkan kualitas hidup penderita dan menghalangi pemberian kemoterapi yang optimal. Suatu alat skrining dengan tingkat akurasi mendekati alat elektroneurografi (ENG) dibutuhkan untuk mendeteksi NPTK secara dini. Skor Toronto clinical scoring system (TCSS) merupakan alat skrining sederhana dan terbukti unggul untuk pemeriksaan neuropati pada diabetes melitus (DM). Kesamaan gambaran klinis antara neuropati DM dengan NPTK dapat menjadikan TCSS sebagai alat skrining untuk NPTK.
Tujuan: Mencari nilai ROC, senstivitas dan spesifisitas TCSS dibandingkan dengan standar baku pemeriksaan ENG.
Metode penelitian: Penelitian berupa uji diagnostik skor TCSS pada penderita keganasan yang mendapat kemoterapi cisplatin di poli hematoonkologi dan ruang perawatan kemoterapi RS Ciptomangunkusumo. Pemeriksaan ENG dan skor TCSS dilakukan pada setiap subjek. Hasil dianalisa untuk mendapatkan kurva ROC, sensitivitas dan spesifisitas.
Hasil: Dari 77 subjek, terdapat 66 yang dapat dianalisa. Diagnosis polineuropati dengan menggunakan ENG sebanyak 34 (51,5%), begitu juga dengan menggunakan TCSS (51,5%). Komponen abnormal TCSS terbanyak adalah komponen pemeriksaan refleks tendon (78,8%). Dari analisa uji diagnostik didapatkan nilai AUC 75,4%, sensitivitas 79,4%, spesifisitas 59,4%, nilai prediksi positif 67,5% dan nilai prediksi negatif 73,1%, dengan titik potong optimal ≥ 5.
Kesimpulan: Skor TCSS memiliki nilai diagnostik yang cukup baik sebagai alat skrining pada NPTK. Skor ini juga memiliki nilai titik potong optimal yang sesuai dengan karakteristik klinis NPTK dan komponen yang dapat digunakan untuk mendeteksi gejala awal NPTK.

Background: Chemotherapy induced peripheral neuropathy (CIPN) is an adverse effect of neurotoxic chemotherapy that lower the patient’s quality of life and prevent optimal chemotherapy. Early detection by a screening tool that have a near accuracy to electroneurography (ENG) is needed. The Toronto clinical scoring system (TCSS) is a simple and superior tool for screening diabetic neuropathy. Similarity between diabetic neuropathy and CIPN’s clinical picture could make the TCSS as screening tool for CIPN.
Purpose: to discover the ROC, sensitivity and specificity of TCSS compared to the ENG as gold standard.
Methodology: the study is a diagnostic test of TCSS in cancer patients with cisplatin from Hematooncology clinic and chemotherapy ward of RSCM. ENG test and TCSS examination were done for each subject. Results were analyzed for ROC, sensitivity and specificity.
Result: out of 77 subjects, only 66 were analyzed. CIPN were diagnosed in 34 (51,5%) by ENG, and also in 34 (51,5%) by TCSS. The most abnormal component of TCSS is the tendon reflex examination (78,8%). The diagnostic analysis acquire the AUC 75,4%, 79,4% sensitivity, 59,4% specificity, positive predictive value of 67,5% and negative predictive value of 73,1%. The optimal cut off point is ≥ 5.
Conclusion: The TCSS is a passable screening tool for CIPN. It also have optimal cut-off point which resemble CIPN’s clinical characteristics and component which can be use to detect early signs.

"This book will introduce design methodologies, known as Built-in-Self-Test (BiST) and Built-in-Self-Calibration (BiSC), which enhance the robustness of radio frequency (RF) and millimeter wave (mmWave) integrated circuits (ICs). These circuits are used in current and emerging communication, computing, multimedia and biomedical products and microchips. The design methodologies presented will result in enhancing the yield (percentage of working chips in a high volume run) of RF and mmWave ICs which will enable successful manufacturing of such microchips in high volume."

"This book will introduce new techniques for detecting and diagnosing small-delay defects in integrated circuits. Although this sort of timing defect is commonly found in integrated circuits manufactured with nanometer technology, this will be the first book to introduce effective and scalable methodologies for screening and diagnosing small-delay defects, including important parameters such as process variations, crosstalk, and power supply noise."
