Accurate Temperature Sensing with an External P-N Junction

January 31, 2013 // By Michael Jones, Linear Technology
Why should you worry about implementing temperature sensing? Can't you just put the sensor near your inductor and lay out your circuit any way you want? Unfortunately, poor routing can sacrifice temperature measurement performance and compensation. The purpose of this ap- plication note is to allow you the opportunity to get it right the first time, so you don't have to change the layout after your board is fabricated.
