Title: Multistep flash analog to digital converter with voltage estimator
Inventor: CHIN SING W
IPC: H03M1/20
Filed: 1989-09-29
Granted: 1992-12-22
Abstract: MULTISTEP FLASH ANALOG TO DIGITAL  CONVERTER WITH VOLTAGE ESTIMATOR             ABSTRACT OF THE DISCLOSURE A novel multistep flash analog to digital converter is taught, including a voltage estimator which quickly provides a rough estimate of the analog input signal. This rough estimate is used to select appropriate reference voltage tap points for use in the first flash conversion.  This first flash conversion, together with the voltage estimate, provides the most significant bits of the digital output word.  A digital to analog converter is used to provide a residual voltage which is then converted by a second operation of the flash converter, thereby providing the least significant bits of the digital output word.  In one embodiment, the voltage estimate is performed at the same time that the analog input signal is sampled by the flash converter in preparation for the first flash conversion.  Therefore, speed of operation is not degraded by the addition of the voltage estimator.

Abstract: Dispositif électrique échangeur de chaleur comprenant plusieurs plaques métalliques conductrices d'électricité, montées côte à côte et séparées l'une de l'autre par des espaceurs en matériau diélectrique, chacun reliant deux plaques avoisinantes. Chacune de ces plaques possède plusieurs sections conductrices formant des parcours de courant dans la plaque de sorte que le courant circulera le long d'un parcours allongé prédéterminé au travers de cette dernière. Les plaques possèdent plusieurs trous, tout au moins au long du parcours allongé, destinés au passage d'un fluide par convection sous pression, faisant en sorte que le fluide soit chauffé par les plaques. Les trous diminuent la surface conductrice en coupe de la plaque, augmentant ainsi sa résistance électrique. Des connecteurs électriques sont prévus pour relier les plaques en série entre elles à des extrémités opposées du parcours allongé. Des connecteurs sont prévue pour relier les plaques à une source de courant électrique afin de chauffer les plaques par effet Joule.
