Claim 12:
13. The temperature detection method of claim 12, where producing the first over-temperature signal at the output node of the first threshold detector comprises providing the first bias current at a first output circuit branch comprising a fifth PFET connected between an input node of the output branch and the output node which is connected to the second bias current,
where the first PFET, third diode-connected PFET, and fifth PFET have gate terminals connected in common to a drain terminal of the third diode-connected PFET to produce the first over-temperature signal at the output node connected to a drain terminal of the fifth PFET in response to the first and second input voltages VS1, VS2 only when the startup bias circuit and current conveyor are connected and activated to form the closed loop.
