The paper presents the structure and control algorithms of a modular designed high-current current source designed for precision measurement of the quality of the magnetic field in magnetic elements designed and
High-precision switched-mode power supplies that are used to feed particle accelerator electromagnets can be broadly classified into two categories: The hardware development of these kind of slow-ramped power systems possess a number of challenges in terms of waveform quality (current needs to be reg...
The MAX6341's reference with an initial accuracy of 4.096 ±0.001 is also much better than the MAX11046's internal reference at 4.096 ±0.0016, thus allowing improved DAS precision and thermal stability. The MAX11046's reference input current in the external-reference mode is only ±10µA...
Successive-approximation (SAR) ADCs offer high resolution, excellent accuracy, and low power consumption. Once a particular precision SAR ADC has been chosen, system designers must determine the support circuitry needed to obtain the best results. The three principal areas to consider are the front ...
The PCB Rogowski sensor is advantageous for isolated current measurement due to its very high bandwidth of 20 MHz and fast settling time of 50 ns. The auto-zeroing, 12-nV/√Hz noise density of the INA188 makes it suitable to achieve a 12-bit system resolution for a full-scale current ...
To achieve wide dynamic input measurement within specified accuracy, ADC with PGA or a high-resolution ADC are used. In this design a 24-bit delta-sigma ADC is used. 1.5 Increasing Analog Input Channels Depending on the protection relay configuration and application, the number of current and ...
The accelerated inverse design of complex material properties—such as identifying a material with a given stress–strain response over a nonlinear deformation path—holds great potential for addressing challenges from soft robotics to biomedical implant
Place a Design View to show a specific area of the board. This example has been scaled to 200%.The PCB Design View object is a graphic snapshot of any rectangular-shaped region of the current board or another board. It can be placed anywhere in the design space and scaled to any size...
The overall precision of a high-resolution, successive-approximation ADC depends on the accuracy, stability, and drive capability of its voltage reference. The switched capacitors on the ADC’s reference input present a dynamic load, so the reference circuit must be able to handle time- and ...
This is one of the common pain points encountered in designing a precision data acquisition signal chain. The benefits of high-Z mode are low input current for slow (<10 kHz) or dc type signals and improved distortion (THD) performance over an input frequency range up to 100 kH...
