Quantum simulation can be implemented in pure digital or analog ways, each with their pros and cons. By taking advantage of the universality a route efficiency simulation, hybrid digital-analog approaches enrich possibilities for quantum simulation. We use unique approach to experimentally perform phase-controlled dynamics resulting from closed-contour interaction (CCI) within certain multi-lev...

Millimeter-wave (MMW) is a probable technology for the future cellular systems. Its main challenge is achieving sufficient operating link margin, and directional beamforming with large antenna arrays may be a viable approach. With bandwidths on the order of gigahertz, high-resolution analog-to-digital converters are a power consumption bottleneck. One solution is to employ an hybrid implementat...

Millimeter wave (mmWave) spectrum has drawn attention due to its tremendous available bandwidth. The high propagation losses in the mmWave bands necessitate beamforming with a large number of antennas. Traditionally each antenna is paired with a high-speed analog-to-digital converter (ADC), which results in high power consumption. A hybrid beamforming architecture and one-bit resolution ADCs ha...

Informal Definitions: • From the point-view of computer scientists: A hybrid system consists of a discrete program within an analog environment [1]; • From the point-view of system scientists: (Supervisor) Hybrid dynamic systems consist of two types of systems, a continuous state system called the plant and a discrete event system called the supervisor, which interact with each other through an...

In this paper we demonstrate a potential extension of formal verification methodology in order to deal with time-domain properties of analog and mixed-signal circuits. The dynamic behavior of an analog circuit can be described by a system of differential algebraic equations. To model and analyse such circuits under all possible input signals and all values of parameters, we apply various techni...

In this paper we revisit hybrid analog-digital precoding systems with emphasis on their modelling and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G system implementations. For this, we decompose the analog beamforming networks (ABFN) as a bank of commonly used RF components and formulate realistic model constraints based on their S-parameters. Specifically, we conc...

Hybrid digital/analog architecture and lowresolution analog-to-digital/digital-to-analog converters (ADCs /DACs) are two low-cost implementations for large-scale millimeter wave (mmWave) systems. In this paper, we investigate the problem of constant-envelope transmit beamforming multiple-input multiple-output (MIMO) radar system, where array adopts a hybrid with small number RF chains receive f...

In this paper, we introduce a new touch sensor design, which we refer to as hybrid tactile sensing. Hybrid tac-tile sensing combines the simplicity of analog touch sensing , which is widely used in electronic touch screens and touchpads, with the ability of shape discrimination of the array touch sensing, found in tactile sensors designed for robotics applications. We describe the construction ...

Both industry and the academic world are becoming more and more interested in techniques to model, analyse, and control complex systems that contain both analog and logical components. Such systems are called hybrid systems. Examples of hybrid systems are telecommunication networks, flexible production systems, parallel processing systems, traffic networks, and so on. In this paper we present a...
