Abstract

A circuit used for indicating process corner and extreme temperature mainly comprises a proportional to absolute temperature (PTAT) current source, a negative to absolute temperature (NTAT) current source, a constant to absolute temperature (CTAT) current source, a corner detector, a poly detector, an extreme temperature detector. The circuit can improve more power consumption without trade-off. In debug phase, the circuit can read out a state of a suspect sample and can run simulation check quickly to identify the real problem. In production phase, the circuit can easily read out at a processing station. In the mean time, a large quantity of data can be easily collected and analyzed.
