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.

Input-output buffer tracking circuitry

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.

Gate bias stabilization techniques

In a particular implementation, an apparatus to control clamping devices includes a detection circuitry, a clamping device, inverter circuitry, and first and second control circuitry. In response to a first voltage corresponding to a gate terminal of the clamping device, the first control circuitry is configured to generate a second voltage to set the first voltage below a first voltage threshold. Also, in response to the second voltage, the second control circuitry is configured to generate a third voltage to set a voltage of the detection circuitry below a second voltage threshold.
