Title:
ワイヤレス温度センサ
Document Type and Number:
Japanese Patent JP2010506183
Kind Code:
A
Abstract:
The invention relates to an integrated temperature sensor (1) comprising:
means (2000) for generating a pulse train (DATA_IN) at an oscillation frequency, means (3000) for counting the number of pulses during a fixed period of time independent of a temperature to be measured (T) and for generating a plurality of
bits (b 11 , b 10 ,..., b 0 ) indicating the number of pulses in the pulse train (DATA_IN),
and means (4000) for generating a serial digital signal (DATA_OUT) from said bits
(b 11 , b 10 ,..., b 0 ), in which the means (2000) for generating a pulse train (DATA_IN) include a plurality of logic gates (2410, 2420, 2430, 2440, 2450) which can introduce a delay dependent on the temperature to be measured (T), said means
(2000) generating a pulse train (DATA_IN) the oscillation frequency of which is dependent on said temperature to be measured (T). The invention also relates to
a temperature measurement method and to a transponder for a wireless system.
