“…In this work, low-cost, professional-grade 6 GHz and 8.5 GHz PicoVNA ® Vector Network Analyzers (VNA) (Pico Technology, Cambridge, UK) and open-source software were selected to acquire the data. These instruments are based on time domain reflectometry and a non-destructive measurement method [ 45 , 46 ]. They calculate the impedance by analyzing the scattering (or S parameters) due to transmitted and reflected energy across the device under test (DUT).…”

Active medical devices rely on a source of energy that is applied to the human body for specific purposes such as electrosurgery, ultrasounds for breaking up kidney stones (lithotripsy), laser irradiation, and other medical techniques and procedures that are extensively used. These systems must provide adequate working power with a commitment not to produce side effects on patients. Therefore, the materials used in these devices must effectively transmit energy, allow for security control, sense real-time variations in case of any issues, and ensure the implementation of closed-loop systems for control. This work extends to the experimental data adjustment of some different coating techniques based on plasma electro-oxidation (PEO) and thermal spray (TS) using fractional-order models. According to the physical structure of the coating in different coating techniques, Cole family models were selected. The experimental data were obtained by means of a vector network analyzer (VNA) in the frequency spectrum from 0.3 MHz to 5 MHz. The results show that some models from the Cole family (the single-dispersion model and inductive model) offered a goodness of fit to the experimental impedance in terms of RMSE error and a squared error R2 close to unity. The use of this type of fractional-order electrical model allows an adjustment with a very small number of elements compared to integer-order models, facilitating its use and a consequent reduction in instrumentation cost and the development of control devices that are more robust and easily miniaturized for embedded applications. Additionally, fractional-order models allow for more accurate assessment in industrial and medical applications.

“…For example, steadily advancing gate density and clock speed of modern ASIC's and FPGA's has led to new demands on their power distribution networks (PDNs). The need to maintain power integrity in the presence of high-speed current transients has forced designers to pay close attention to the impedance associated with both on-and off-chip PDN [1][2][3]. This often requires measurement of single-digit milli-ohm impedances that present substantial challenges using even the most advanced available test equipment [4].…”

Fixturing impacts on high‐frequency low‐resistance, low‐inductance impedance measurements

2016

Multiple off-the-shelf test-fixtures are available to interface a deviceunder-test (DUT) to an impedance analyser to characterise its electrical properties. The impact of three available fixtures on the measured impedance of a low-resistance, low-inductance DUT requiring highfrequency (≥100 MHz) characterisation are compared with a custom fixture. The custom fixture is shown to provide a higher accuracy than the off-the-shelf fixtures, highlighting that low-resistance, lowinductance devices require carefully constructed fixtures for characterisation. The experimental results collected using the fixtures are validated against a finite-element-analysis model of the DUT.
