Title:

ELECTRONIC CIRCUIT FOR BIASING AND READING RESISTIVE THERMAL DETECTOR

Document Type and Number:

Japanese Patent JP2012118078

Kind Code:

A

Abstract:

To improve a SN ratio of pixels by reducing noise caused by a reading circuit.

An electronic circuit (100) for biasing and reading at least one resistive thermal detector (102) includes: biasing means capable of biasing the resistive thermal detector by making a biasing current of substantially constant value flow in the resistive thermal detector when the electrical resistance thereof varies; conversion means capable of converting a voltage into a current at the terminals of the resistive thermal detector (102), and comprising at least one MOS-type transistor (106) of which gate is electrically connected to one of the terminals of the resistive thermal detector; and base clipping voltage generating means electrically connected to the source of the MOS-type transistor of the conversion means.
