Not only the active devices are affected by the generated power in electronics but capacitors also suffer from the elevated temperature levels. This paper attempts transferring the concepts of the thermal transient measurement method used in the semiconductor characterization to capacitor components. We show how temperature dependent electrical parameters could be used to measure the temperature of...
Proportional to Absolute Temperature (PTAT) CMOS current sources are widely used in temperature sensors, bandgap references, and other temperature-compensating circuits. Most of these applications strongly rely on the accuracy of a current ratio m established with a set of 1+m PTAT current sources. However, a PTAT CMOS current source has a temperature-dependent bias point, which in turn, has a well-known...
