An integrated circuit includes a memory and peripheral circuits with a temperature sensor used to automatically adjust operating voltages. The temperature sensor includes a reference circuit that generates a first reference with a first non-zero temperature coefficient and a second reference with a second temperature coefficient having a different magnitude than the first non-zero temperature coefficient. A detector circuit on the integrated circuit, having temperature and process variation compensation, converts a difference between the first and second references into a digital signal indicating temperature on the integrated circuit.

Temperature sensor and memory device having same

A metal capacitor provided includes a first metal layer and a second metal layer disposed above a substrate. The first metal layer includes a first electrode sheet and a second electrode sheet, and the second metal layer includes a third electrode sheet and a fourth electrode sheet. The first electrode sheet and the second electrode sheet collectively form a first coplanar capacitor. The third electrode sheet and the fourth electrode sheet collectively form a second coplanar capacitor. At least a portion of the fourth electrode sheet is arranged above the first electrode sheet, and the first electrode sheet and the fourth electrode sheet collectively form a first vertical capacitor. At least a portion of the third electrode sheet is arranged above the second electrode sheet, and the second electrode sheet and the third electrode sheet collectively form a second vertical capacitor.
