Abstract :
This paper presents a 16times16 temperature probe array using 90 nm IV CMOS, which shows plusmn1.4degC error for 40 ~ 110degC temperature range and achieves a temperature distribution measurement at 40 frames/sec. This array is designed and developed for an operating frequency and supply voltage feedback system corresponding to temperature of each block on a VLSI chip. The continuous thermal monitoring is performed by using accurate four-transistor temperature probe circuits with an error amplifier and two PMOS current sources.
