Abstract
An apparatus may include a transistor, a capacitor, and an operational amplifier. The transistor may have a sub-threshold voltage applied to a gate of the transistor. The capacitor configured to store a first gate-to-source voltage of the transistor while a first switch and a second switch are closed and a third switch is open. The capacitor may be charged to a first gate-to-source voltage of the transistor while the transistor is biased with a first bias current. The operational amplifier may be configured to determine a voltage difference between the first gate-to-source voltage stored in the capacitor and a second gate-to-source voltage of the transistor while the transistor is biased with a second bias current. The operational amplifier may determine the voltage difference while the third switch is closed and the first switch and the second switch are open. The voltage difference may correspond to a temperature of the transistor.
