ABSTRACT:
A temperature sensor having one or more mirror circuits output temperature dependent output signals is disclosed in one embodiment. The temperature sensor includes a sampling circuit coupled to receive a clock signal that samples the output signals for a duration of a predetermined number of clock cycles. The temperature sensor additionally includes a phase control circuit that receives the clock signal and generates a control signal that enables subsequent sampling operations. Each subsequent sampling operation has a duration of the predetermined number of clock cycles. The control signal from the phase control circuit further enables input and output terminals of respective circuit components in the mirror circuits to be switched for each subsequent sampling operation.
