MAQOLA ANNOTATSIYASI

Qalin qatlamli rezistorlardan ishlab chiqarilgan tenzodatchik nisbatan yuqori kuchlanish sezuvchanligi, barqarorligi, ishlab chiqarish tannarxi pastligi va uzoq muddatli xizmati tufayli qurilish muhandisligida foydalanish uchun katta imkoniyatlarga ega. Shunga qaramay, tenzodatchiklarning doimiy kamchiliklari ularning termal sezgirligidir. Ushbu muammoni hal qilish uchun past haroratni sezmaydigan qalin qatlamli rezistorlardan tayyorlangan tenzodatchik taklif qilinishi va ishlab chiqarilishi maqsadga muvofiq. Mazkur maqolada rezistorli pasta komponentlari va pishirish haroratining qalin qatlamli rezistorning qarshilik harorat koeffitsiyentiga (TCR) ta’siri tizimli ravishda o‘rganildi. Al2O3 tagligida turli xil haroratlarda pishirilgan RuO2 konsentratsiyasidan 10 wt % dan 30 wt % gacha tayyorlangan qalin qatlamli rezistorlar tekshirildi. Rezistorlar qarshiligi, TCR va o‘lchov omili (GF) o‘rtasidagi munosabatlar o‘rganildi. Natijalar shuni ko‘rsatdiki, RuO2 konsentratsiyasi va pishirish harorati ortishi bilan TCR ham ortadi. Qarshilik-harorat egri chizig‘ining minimal (Tmin) yaqinida harorat qarshilik qiymatiga eng kam ta’sir qiladi va qalin qatlamli rezistor ma’lum bir diapazonda haroratga sezgir emas deb hisoblash mumkin. TCRning GF va Tminga nisbati qalin qatlamli rezistorlarning qatlam qarshiligiga bog‘liq. Supero‘tkazuvchilar faza konsentratsiyasi va pishirish haroratini o‘zgartirishi orqali qalin qatlamli rezistorlarning qatlam qarshiligini nazorat qilish mumkin. So‘ngra turli xil muhit haroratlari uchun past haroratlarni sezmaydigan tenzodatchiklar olishga erishiladi.
