“…The reliability of technical objects (which is a separate scientific domain) considers fuse-links to be an anti-damage subsystem (alternatively dubbed as anti-failure) [38][39][40]. Solutions that directly precede its tripping are, above all, shielding and intervention subsystems [41][42][43][44].…”

Miniature fuses as an anti-damage subsystem perform the important function of protecting electronic devices and systems against permanent damage that may result in electric shocks, fire risks, etc. Their role becomes particularly important when they are installed in such special systems as electronic security systems (ESS). For this reason, there is a need for practical verification of their protective properties. The article presents the results of destructive tests of the circuit-breaking time of miniature fuse-links considered in terms of their usefulness in the ESS with the use of a passive experimental add-on, developed at the Military University of Technology in Warsaw. The characteristics of the measuring attachment circuit and the measurement methodology used were presented. Based on the obtained measurement points of the obtained time–current characteristics, an attempt was made to develop their mathematical model using numerical methods in the field of non-linear regression, using the least squares optimization method (Levenberg–Marquardt algorithm). An exemplary classification of miniature fuse-links has been proposed due to their protective properties of circuits in the context of their use in electronic security systems. The considerations were summarized with an economic analysis of the tested fuse links. The conclusions include proposals for changes to the provisions of the European standard PN-EN 50131-1:2009 “Alarm systems: Intrusion and hold-up systems Part 1: System requirements” and Polish Defence Standard NO-04-A004-8 2016 “Military facilities. Alarm systems. Part 8: Operation”.

“…Electrical resistance of the fuse after it blows increases approximately a million times. In [9], an NMOS transistor controlled by a NOR gate is used to blow the fuse. In [10], the fuse blowing by connecting voltages of 1.5 V and 2 V is shown as illustrative comparison.…”

This article deals with the calibration method of analog integrated circuits (ICs) designed in CMOS nanotechnology. A brief analysis of various methods and techniques (e.g., fuse trimming, chopper stabilization, auto-zero technique, etc.) for calibration of a specific IC’s parameter is given, leading to motivation for this research that is focused on the digital calibration. Then, the principle and overall design of the calibration subcircuit, which was generally used to calibrate the input offset voltage VIN_OFF of the operational amplifier (OPAMP). The essence of this work is verification of the proposed digital calibration algorithm for minimization the VIN_OFF of a bulk-driven fully differential difference amplifier (FDDA) with the power supply voltage VDD = 0.4 V. Evaluation of ASIC prototyped chip samples with silicon-proved results has been done. This evaluation contains comparison of selected parameters and characteristics obtained from both simulations and measurements of non-calibrated and calibrated FDDA configurations.

“…If the circuit requires a calibration, the additional calibration elements are added to the circuit by blowing the fuses. The disadvantages of this method include the increased area of the sub-circuit and its invasive character, as the fuses are blown by a laser or high current [14] [15].…”

This work presents a dedicated method of analog integrated circuit (IC) autocalibration, which was used to calibrate a voltage reference with the output voltage value of 96 mV . The reference accuracy might be significantly influenced by fluctuations in the manufacturing process. The essence of this technique is to suppress this undesired influence of process variations in terms of the corner conditions of 130 nm CMOS technology. All analog parts of the proposed autocalibration system are presented at the transistor level. The output of the calibration subcircuit is a digital signal controlling the autocalibration.
