A monolithic active pixel sensor operating in current mode for charged particle detection is described. The sensing element in each pixel is an n-well/p-sub diode with a PMOS transistor integrated in an n-well. The drop of the n-well potential from the collection of charge modulates the transistor channel current. Each pixel features two current mode memory cells. The subtraction of distant-in-...

Increased pressure for low power, small form factor, low cost and reduced bill of materials in such radio applications as mobile communications has driven academia and industry to resurrect the direct conversion receiver. Long abandoned in favor of the mature superheterodyne receiver, direct conversion has emerged over the last decade or so thanks to improved semiconductor process technologies ...

High data rates, low-power consumption, and low complexity will be the most important parameters in the design of the nextgeneration mobile terminals. In this paper we are introducing a new paradigm in the design of direct sequence spread spectrum receiver by combining analog and digital signal processing. Themain difference with respect to the conventional all-digital receiver design approach ...

This letter revisits a Hopfield network for an SAR ADC configuration, which enables low voltage, power and fast operation with small circuitry. It employs asymmetrical to avoid local minimum, it uses capacitors switches instead of very large resistors. Our N-bit N chopper-type comparators asynchronous parallel operation, is different from the conventional employing only one comparator. requires...

This project explores the design of a type of direct-conversion ADC called a Residue Amplifier Pipeline ADC. Direct-conversion ADCs are a class of ADCs that operate at very high speeds, because the input signal is converted to a digital value in a single iteration. Other types of ADCs require many comparison iterations to convert the signal, resulting in much slower conversion times. This desig...

A systematic comparative study of audio to visual speech conversion methods is described in this paper. A direct conversion system is compared to conceptually different ASR based solutions. Hybrid versions of the different solutions will also be presented. The methods are tested using the same speech material, audio preprocessing and facial motion visualization units. Only the conversion blocks...

We find infant faces highly attractive as a result of specific features which Konrad Lorenz termed "Kindchenschema" or "baby schema," and this is considered to be an important adaptive trait for promoting protective and caregiving behaviors in adults, thereby increasing the chances of infant survival. This review first examines the behavioral support for this effect and physical and behavioral ...
