“…For implanted devices, the radio frequency identification (RFID) readers can receive the data, and provide suitable power. In [ 42 ], a structure for the RFID reader was presented where it included Class-E/Fodd PAs and incorporated a single-segmented antenna in the receiver and transmitter sections, which operate simultaneously. The typical efficiency of the design is 54%.…”

Continuous monitoring and treatment of various diseases with biomedical technologies and wearable electronics has become significantly important. The healthcare area is an important, evolving field that, among other things, requires electronic and micro-electromechanical technologies. Designed circuits and smart devices can lead to reduced hospitalization time and hospitals equipped with high-quality equipment. Some of these devices can also be implanted inside the body. Recently, various implanted electronic devices for monitoring and diagnosing diseases have been presented. These instruments require communication links through wireless technologies. In the transmitters of these devices, power amplifiers are the most important components and their performance plays important roles. This paper is devoted to collecting and providing a comprehensive review on the various designed implanted amplifiers for advanced biomedical applications. The reported amplifiers vary with respect to the class/type of amplifier, implemented CMOS technology, frequency band, output power, and the overall efficiency of the designs. The purpose of the authors is to provide a general view of the available solutions, and any researcher can obtain suitable circuit designs that can be selected for their problem by reading this survey.

“…Compression of point processes emerges naturally in several of the above domains. Subcranial implants need to communicate the timing of neural firings to a monitoring station over a wireless link that is low-rate because it must traverse the skull [24], [25]. In network flow correlation analysis, one cross-correlates packet timings from different links in the network [11]; this requires communication of the packet timings from one place to another.…”

We introduce a new distortion measure for point processes called functional-covering distortion. It is inspired by intensity theory and is related to both the covering of point processes and logarithmicloss distortion. We obtain the distortion-rate function with feedforward under this distortion measure for a large class of point processes. For Poisson processes, the rate-distortion function is obtained under a general condition called constrained functional-covering distortion, of which both covering and functional-covering are special cases. Also for Poisson processes, we characterize the rate-distortion region for a two-encoder CEO problem and show that feedforward does not enlarge this region. I. INTRODUCTIONThe classical theory of compression [2] focuses on discrete-time, sequential sources. The theory is thus well-suited to text, audio, speech, genomic data, and the like. Continuous-time signals are typically handled by reducing to discrete-time via projection onto a countable basis. Multi-dimensional extensions enable application to images and video. Point processes model a distinct data type that appears in diverse domains such as neuroscience [3]-[8], communication networks [9]-[11], imaging [12], [13], blockchains [14]-[17],and photonics [18]- [22]. Formally, a point process can be viewed as a random counting measure on some space of interest [23], or if the space is a real line, a random counting function; we shall adopt the latter view. Informally, it may be viewed as simply a random collection of points representing epochs in time or points in space.
