In recent years, sensing targets around the corner of walls and other types of blockages by radar for surveillance purposes is being increasingly researched [1]–[4]. The around the corner radar (ACR) is a recent development when compared to through wall radar (TWR) [5] and indoor radar [6] technologies. Typically, indoor radars are characterized by low carrier frequencies and bandwidths of the order of few hundreds of MHz resulting in range resolution in the order of meters.These radars have usually relied on Doppler information for inferring the type of activity undertaken by the target [7]–[9] while range and azimuth information have been gathered for localizing and imaging the target.

This paper presents a novel mostly passive Δ-Σ ADC using amorphous Indium Gallium Zinc Oxide (a-IGZO) thin-film transistors (TFTs). The ADC circuit consists of passive elements (resistors and capacitors), a novel dynamic comparator, a D-Flip Flop and a pseudo-CMOS BS inverter. In-house oxide TFT model is used for circuit simulations in Cadence environment. The proposed ADC results in effective-number-of-bits (ENOB) of 11.2 bits and a figure-of-merit (FOM) of 0.15 µJ/conversion step at 2 kHz sampling frequency with a 10 V power supply. This circuit would find potential applications in biomedical wearable systems, in which, the ADC is probably the most important block.

Owing to the non-overlapping spectrum, Light fi-delity (LiFi) and WiFi technologies can coexist and form a hetero-geneous LiFi WiFi network (HLWN). The performance of HLWN significantly depends upon the load balancing strategies. Since Load balancing of HLWN is a non-convex mixed-integer nonlinear programming (MINLP) optimization problem, it is mathemati-cally intractable, and therefore, the conventional optimization methods fail to provide an optimal global solution. Although an optimal solution can be obtained using the exhaustive search method, it would be computationally complex. Therefore, in this paper, a reinforcement learning (RL) based algorithm is explored for solving the load balancing problem for the downlink HLWN at reasonably low complexity and near optimal performance.

In the design and development of front-end communication systems, the arbitrary impedance environments are encountered frequently. In this article, a three-port dual-band equal power divider is proposed which also transforms all types of impedance environments at its ports inherently. The power divider is suitable for a wide range of arbitrary frequency ratios and impedance terminations at each of the input and output ports. A systematic design procedure with a design flow graph is provided. The closed-form design equations make the design process simple and quick for prototyping purposes.
