Abstract
Official abstract text for this publication.
A system includes first circuitry including first elements for operating in a low power mode; second circuitry including second elements for operating in a high-temperature mode; and one or more switching elements for selecting between the low power mode and the high temperature mode.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for ensuring operation of low power circuits at high temperature, comprising: circuit elements that are sensitive to high temperatures, further comprising an oscillator comprising a current reference and a ramp generator that can be controlled to operate in a first mode and in a second mode to generate said output signal, wherein the first mode is a low power mode and the second mode is a high temperature mode, wherein the oscillator comprises a con…
