Abstract

Some embodiments include apparatuses and methods having a node to receive ground potential, a first diode including an anode coupled to the node, a second diode including an anode coupled to the node, a first circuit to apply a voltage to a cathode of each of the first and second diodes to cause the first and second diodes to be in a forward-bias condition, and a second circuit to generate a signal having a duty cycle based on a first voltage across the first diode and a second voltage across the second diode. At least one of such the embodiments includes a temperature calculator to calculate a value of temperature based at least in part on the duty cycle of the signal.
