“…Due to their mixed advantages in resolution, speed, power, and cost, SAR ADCs are widely applied in industry controlling, medical instruments, auxiliary analogue-to-digital interfaces of microprocessors, and so on [11,12]. In recent years, FPGA with the advantages of design flexibility and adaptability is the current trend for the digital implement [13][14][15]. As shown in Figure 1, the multichannel acquisition system is composed of a single high speed SAR A/D converter, a FPGA module, a flash storage module, a USB controller module, several analogue multiplexers, and signal conditioners.…”

The paper proposes an efficient multiplexing scheme that is easy to realize synchronous sampling in a multichannel acquisition system with the large number of analogue inputs and different sampling rates. And then, a simple improved sampling control method is also employed to improve the performance. All the technology of implementing the method is by using a low-cost field programmable gate array (FPGA). A sampling lookup table is built by the rule-based synchronous sampling frame structure for the input analogue multiplexers and stored into the internal block RAM resource in the FPGA to reduce the internal wiring resources and optimize the utilization. The improved sampling method obtains several samples in a sampling period and gets the average value as the final output for the sampling channel. In addition, the standard sine wave FFT test method is implemented to test the dynamic parameters of the acquisition channels. The experiment results show that the dynamic performance of the acquisition system is significantly improved. The proposed multiplexing scheme and sampling method can easily be reconfigured for other applications.

“…Different digital electronics techniques have been used in lab-on-chip applications; these techniques are based on programmable logic devices and microcontrollers. Programmable resources can be optimized to support a target embedded application without the time and cost of designing a custom application-specific integrated circuit [20], [21].…”

Interventional radiologists and staff members, during all their professional activities, are frequently exposed to protracted and fractionated low doses of ionizing radiation. Due to skin tissues and peripheral blood irradiation, these exposures can result in deterministic effects (radiodermatitis, aged skin, and hand depilation) or stochastic ones (skin and non-solid cancer incidence). The authors present a novel approach to perform online monitoring of the staff during their interventions by using a device based on an Active Pixel Sensor. The performance of the sensor as an X-ray radiation detector has been evaluated with a proper experimental setup: the number of photons and the generated charge have been assessed as dosimetric observables from the frames acquired by the sensor using a two-threshold clustering algorithm, the efficiency of which has been evaluated as well. The correlation of these observables with passive dosimeter dose measurements has been analyzed: a good linearity has been demonstrated, and the response difference between pulsed and continuous operational modes is reduced to less than 10%, marking a distinct improvement with respect to commercial Active Personal Dosimeters.Index Terms-Active Personal Dosimeter, CMOS pixels, dosimetry, interventional radiology (IR), X-ray.

“…Instead of using multiple ADC for simultaneous multi-channel data acquisition, the proposed design uses a single high speed ADC along with a multiplexer to perform quasi-simultaneous data acquisition. In the medical field for example, where various biomedical signals are in the low frequency range from 25 Hz to 5 KHz Abdallah et al (2009), the proposed DAQ can be appropriate without the need of additional hardware or cost. For applications that require very fast simultaneous multi-channel data acquisition, such as in the military field, dedicated ADC per channel will be more appropriate.…”
