A circuit for fast, compact and low-power focal-plane motion centroid localization is presented. This chip, which uses mixed signal CMOS.

We detail the design, simulation, layout, and testing of four analog VLSI subaperture centroid circuits for use in an adaptive optics system. Each centroid ...

We present a circuit that uses this aggregation network to compute the centroid of a visual image. We develop a theoretical basis for analyzing this circuit ...

X and Y IP as shown in figure 1. A single divider circuit is then used to generate the X and Y centroids. The X- and the Y-centroids computed by the ...

The DEM algorithm, commonly used in ADC and DAC circuits, allows reducing the required WTA circuit precision to 5–6 bits, while still achieving a high output ...
