Title:
ANALOG DEVICE, METHOD FOR CONTROLLING SAME, TEMPERATURE SENSOR, AND ANALOG-ELEMENT-ASSOCIATED SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/090860
Kind Code:
A1
Abstract:
The present invention estimates the value of a threshold-value voltage of a transistor related to operation of a temperature sensor. Each of a plurality of transistors (Mn) that perform analog operations has: a threshold-value voltage related to operation of a temperature sensor (1), the threshold-value voltage being such that variation therein follows a statistical distribution; and a sub-threshold leak current corresponding to the threshold-value voltage. A control device (2) sequences the plurality of transistors (Mn) in accordance with a measurement value of the sub-threshold leak current, and associates the value of the threshold-value voltage and the transistors (Mn) on the basis of the statistical distribution pertaining to the threshold-value voltage and the sequence of the transistors (Mn).
