Abstract: Various implementations described herein are related to a device having a level shifter that receives an input signal and reference voltages and provides level-shifted input signals based on the reference voltages. The device may have a pre-driver that receives the level-shifted input signals and reference voltages and provides gate voltages based on the reference voltages. The device may have a gate stabilizer that receives the reference voltages and provides a stabilized reference voltage based on the reference voltages. The device may have an output driver that receives the reference voltages, receives the gate voltages, receives the stabilized reference voltage and provides an output pad voltage to an input-output pad based on the reference voltages, the gate voltages and the stabilized reference voltage.

Abstract: Various implementations described herein are directed to a device having an input-output pad configured to receive and supply an input-output pad voltage. The device may include gate tracking circuitry that receives a first voltage, receives a second voltage different than the first voltage, receives node voltages and provides a first tracking voltage and a second tracking voltage based on the first voltage, the second voltage and the node voltages. The device may include output circuitry that receives the first tracking voltage and the second tracking voltage from the gate tracking circuitry and provides the input-output pad voltage to the input-output pad based on the first tracking voltage and the second tracking voltage.

Abstract: Various implementations described herein are related to a device with a bias generator that receives a pad control signal, receives an output pad voltage as a pad feedback signal from an output pad, and provides bias voltage signals based on the pad control signal and the pad feedback signal. The device may have a bias driver that receives the bias signals from the bias generator and provides the output pad voltage to the output pad based on the bias signals. The device may have a pad voltage detector that receives the output pad voltage as the pad feedback signal from the output pad and provides the pad control signal to the bias generator based on the pad feedback signal.
