  • Publication number: 20090251103
    Abstract: In a voltage detecting apparatus, a voltage controlled oscillator, when an input voltage is applied thereto, outputs a signal with a logical value that is periodically inverted. A detector counts a number of logical inversion of the output signal from the voltage controlled oscillator over an interval between edges of pulses of a pulse signal to thereby generate, based on the counted number of logical inversion, digital data as a detected result of the input voltage. A determiner determines whether a reduction of a time required to detect the input voltage is higher in priority than an increase of a resolution of detection of the input voltage. A variably setting unit variably sets a frequency of the pulse signal based on a result of the determination of whether the reduction of the time required to detect the input voltage is higher in priority than the increase of the resolution of detection of the input voltage.

  • Publication number: 20090195430
    Abstract: In an A/D converting apparatus, a converting unit has an input terminal and an input-output characteristic. The input-output characteristic has temperature dependence, and the converting unit carries out a process of converting an input voltage signal to digital data. A temperature determining unit has information representing a relationship between a variable of an output of the converting unit and a variable of a temperature around the converting unit according to the temperature dependence of the input-output characteristic of the converting unit. When the specified voltage is applied to the input terminal of the converting unit, the temperature determining unit determines a value of the temperature around the converting unit based on the information and the specified voltage. A reducing unit reduces temperature dependence of the process of converting an input voltage signal to digital data based on the determined value of the temperature around the converting unit.
