20.500.12556/DiRROS-30236 Design of a new MISO mixed-mode universal biquad OTA-C filter in 130nm CMOS technology Oblikovanje novega MISO univerzalnega biquad OTA-C filtra z mešanim načinom v 130 nm tehnologiji CMOS This paper presents the design of a MISO (multiple-input single-output) universal biquad filter in 130 nm CMOS UMC technology. The proposed filter consists of three operational transconductance amplifiers (OTAs), two grounded capacitors and one inverter stage. The topology, which has three inputs and one output, operates in all modes: voltage, transconductance, current, and transresistance. In addition, the filter generates all types of transfer functions (LP, HP, BP, BS, and AP). First, the filter topology with an inverter at the output is designed and analyzed in detail. Next, an improved topology with a differential amplifier as the output stage is proposed. The designed filter has a cutoff frequency of approximately 250 MHz and a current consumption of 4.5 mA. The impact of process, temperature, and voltage variations is examined through corner analysis. V tem članku je predstavljena zasnova univerzalnega biquad filtra MISO (multiple-input single-output) v 130 nm tehnologiji CMOS UMC. Predlagani filter je sestavljen iz treh operacijskih transkonduktančnih ojačevalnikov (OTA), dveh ozemljenih kondenzatorjev in ene inverterske stopnje. Topologija, ki ima tri vhode in en izhod, deluje v vseh načinih: napetostnem, transkonduktančnem, tokovnem in tranzistorskem. Poleg tega filter ustvarja vse vrste prenosnih funkcij (LP, HP, BP, BS in AP). Najprej je zasnovana in podrobno analizirana topologija filtra z inverterjem na izhodu. Nato je predlagana izboljšana topologija z diferencialnim ojačevalnikom kot izhodno stopnjo. Zasnovani filter ima mejno frekvenco približno 250 MHz in porabo toka 4,5 mA. Vpliv procesnih, temperaturnih in napetostnih sprememb je preučen z analizo vogalov universal biquad filter operational transconductance amplifier OTA-C filter analog IC design univerzalni biquad filter operacijski transkonduktančni ojačevalnik filter OTA-C MISO zasnova analognih integriranih vezij true false true Angleški jezik Slovenski jezik Neznano 2026-06-17 19:12:55 2026-06-18 06:00:44 2026-07-02 03:59:35 0000-00-00 00:00:00 2025 0 0 Besedilo v angl.; str. 141-150 no. 3 Vol. 55 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-01-01 621.38 0352-9045 10.33180/InfMIDEM2025.301 281485571 MIDEM_55(2025)3p1.pdf MIDEM_55(2025)3p1.pdf 1 D1A7FEA7618CE63D178A1979E9ED5D98 1d18f3b48cb3302f21dd38cc53d42b06b80780769fe79b2cbefcf1aff37bd371 744751f7-7528-11f1-b0d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46811 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/2131 1 c87ced33-6a6f-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45806 \"https://www.midem-drustvo.si/journal_papers/MIDEM_55(2025)3p1.pdf 1 6a54e4a1-7528-11f1-b0d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46788 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/2131 1 487855d2-6aca-11f1-a3b9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45838 RAZ_Popadic_Goran_2025.pdf RAZ_Popadic_Goran_2025.pdf 1 A483153CCA07F14B4226EEFF273DB8AF d96d049aabe4cbd9aa13429e37f728650535fef5767c7af90f4674552a99d1e3 6ce2789e-7385-11f1-a785-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46406 Strokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale Informacije MIDEM 0 0 0
