This paper gives an overview of some of the effects caused by circuit mismatch and parasitics in binary weighted digital-to-analog (DAC) converters, and, as a special case, a current-steering CMOS converter. Matlab is used as a behavior-level simulator. In telecommunications applications, the frequency-domain parameters are of the greatest importance. Therefore, the characterization of the devi...

Standard sparsity-based algorithms used in power system applications need to be restructured for efficient vectorization due to the extremely short vectors processed. Further, intrinsic architectural features of vector computers such as chaining and sectioning should also be exploited for utmost performance. This paper presents novel data storage schemes and vectorization algorithms that resolv...

This paper presents a distributed consensus-based approach to solve the economic dispatch problem with power generator constraints and transmission losses. Buses and transmission lines in the power system are modeled as nodes and edges in a communication graph, respectively. Each node exchanges information with its neighbors and runs two consensus algorithms in parallel, without relying on a ce...

This paper presents performance analysis of Gated Ring Oscillator (GRO). Proposed GRO is designed to employ in implementation of Time to Digital Converter (TDC) block of Asynchronous ADC. For an audio frequency range ADC, minimum GRO stages are designed using asynchronous technique. So leads to reduced area and power. Compared to conventional Ring Oscillator (RO), we avoided to employ the gated...

Institutions affect prospects for economic growth and development. This paper collapses potentially complex interactions of different institutions into a condition on the primitives that determines whether a society supports markets. Agents differ in land holdings, skill, and power, e.g. physical strength, wealth, or status. A competitive market assigns land efficiently to the skilled, not nece...

This work describes a reconfigurable 10MS/s to 100MS/s, 0.5V to 1.2V, 0.98mm, 10b low-power 0.13um CMOS two-step pipeline ADC. The SHA employs gate-bootstrapped sampling switches and a two-stage amplifier based on a low-threshold NMOS differential input stage to obtain 10b accuracy even at a 0.5V supply. A signal-isolated all directionally symmetric layout reduces the MDAC capacitor mismatch wh...

Plant-herbivore interactions mediate the trophic structure of ecosystems. We use a comprehensive data set extracted from the literature to test the relative explanatory power of two contrasting bodies of ecological theory, the metabolic theory of ecology (MTE) and ecological stoichiometry (ES), for per-capita and population-level rates of herbivory across ecosystems. We found that ambient tempe...

The “Split ADC” architecture enables fully digital calibration and correction of nonlinearity errors due to capacitor mismatch in a Successive Approximation (SAR) ADC. The die area of a single ADC design is split into two independent halves, each converting the same input signal. Total area and power is unchanged, resulting in minimal increase in analog complexity. For each conversion, the half...

This paper proposes an offset-free model predictive control (MPC) method for output voltage regulation of the three phase inverter for an uninterruptible power supply (UPS) application. A use of a disturbance observer (DOB) is made to estimate the unknown disturbance caused by the load current and a plant-model mismatch. The proposed MPC optimizes the one step ahead cost function. The online co...

In this paper the model of hybrid power system is developed. It comprises two thermal power generation system with Photovoltaic generation system (PV), wind turbine, fuel cell, aqua electrolyzer and battery storage system. To maintain the preferred frequency and power exchange with the neighboring system in the hybrid power system is the objective of Automatic Generation Control (AGC). The devi...
