Abstract: Various implementations described herein are related to a device having an output pad that is configured to supply an output pad voltage. The device may include tracking circuitry that is configured to receive a first voltage, receive a second voltage that is different than the first voltage, receive the output pad voltage as a feedback voltage, and provide a first tracking voltage and a second tracking voltage based on the first voltage, the second voltage and the feedback voltage. The device may include output circuitry that is configured to receive the first tracking voltage and the second tracking voltage from the tracking circuitry and provide the output pad voltage to the output pad based on the first tracking voltage and the second tracking voltage.

Abstract: Various implementations described herein are directed to a device having an output pad that provides an input-output (IO) voltage from an IO power supply. The device may include core ramp detection circuitry that detects a first ramp of a core voltage from a core power supply and provides a core ramp sensing signal. The device may include output logic circuitry that couples the output pad to ground after receiving the core ramp sensing signal so as to reduce leakage of the IO power supply.
