This study presents a survey of the most promising reported SAR ADC designs for biomedical applications, stressing advantages, disadvantages, and limitations, and concludes with a quantitative comparison. Recent progress in the development of a single SAR ADC architecture is reviewed. In wearable and biosensor systems, a very small amount of total power must be devoured by portable batteries or energy-harvesting circuits in order to function correctly. During the past decade, implementation of the high energy efficiency of SAR ADC has become the most necessary. So, several different implementation schemes for the main components of the SAR ADC have been proposed. In this review study, the various circuit architectures have been explained, beginning with the sample and hold (S/H) switching circuits, the dynamic comparator, the internal digital-to-analog converter (DAC), and the SAR control logic. In order to achieve low power consumption, numerous different configurations of dynamic comparator circuits are revealed. At the end of this overview, the evolutions of DAC architecture in distinct biomedical applications today can make a tradeoff between resolution, speed, and linearity, which represent the challenges of a single SAR ADC. For high resolution, the dual split capacitive DAC (CDAC) array technique and hybrid capacitor technique can be used. Also, for ultralow power consumption, various voltage switching schemes are achieved to reduce the number of switches. These schemes can save switching energy and reduce capacitor array area with high linearity. Additionally, to increase the speed of the conversion process, a prediction-based ADC design is employed. Therefore, SAR ADC is considered the ideal solution for biomedical applications.

Summary Direct‐current (DC) voltage source is an essential part in many occasions such as integrated systems and laboratory electricity, which can provide a stable and continuous voltage supply. Traditional voltage sources are frequently designed by bipolar junction and field effect transistors. Compared with these devices, memristors have lower power consumption and smaller size. At present, memristors have been used in the design of logic circuits and other functional circuits, which could provide a new idea for applying memristors into the design of DC voltage sources. In this paper, a memristor‐based circuit design of continuously adjustable DC voltage source is proposed for the first time. The proposed DC voltage source circuit only consists of two modules and has a simple structure. In addition, the output voltage amplitude of this voltage source can be continuously adjusted by the application of a control signal due to the utility of the memristor. The operation process of the whole circuit and the mathematical model between the input and output are analyzed in detail, which is greatly beneficial for use and expansion. Finally, the effectiveness of the circuit is verified in PSPICE, and the accuracy of the output amplitude of the voltage source is also investigated.
