Abstract
A low power temperature detection method, system, and apparatus sense when a temperature threshold is reached by connecting a current conveyor () with a startup bias circuit () having a first FET (P) (connected to level shift a reference voltage to provide an input voltage V), a first diode-connected BJT (Q) (connected to generate a base-emitter voltage based on the junction temperature), and a second FET (P) (connected to level shift the base-emitter voltage), where the startup bias circuit () selectively connects the current conveyor () to ground to form a closed loop that is activated only when an emitter current at the first diode-connected BJT (Q) enters a self-turned-on operation region, thereby activating the current conveyor to detect a temperature threshold being reached by the device junction temperature.
