Claim 8:
9. The watchdog circuit of claim 8, wherein
the first temperature sensitive device includes a first plurality of metal oxide semiconductor (MOS) transistors coupled in parallel between the diode device and the common terminal, wherein a body of each respective MOS transistor in the first plurality of MOS transistors is coupled to the diode device and conducts a respective portion of the first leakage current, and each respective source of a first number of the MOS transistors in the first plurality of MOS transistors is coupled to the diode device and conducts respective portions of the first leakage current, and each respective source of a remainder of the first plurality of MOS transistors is unconnected; and
the second temperature sensitive device includes a second plurality of MOS transistors coupled in parallel between the trigger device and the common terminal, wherein a body of each respective MOS transistor in the second plurality of MOS transistors is coupled to a gate of the trigger device and conducts a respective portion of the second leakage current, each respective source of a second number of the MOS transistors in the second plurality of MOS transistors is coupled to the gate of the trigger device and conducts respective portions of the second leakage current, and each respective source of a remainder of the second plurality of MOS transistors is unconnected.
