Downhole tool methods and systems with variable impedance control
A disclosed method includes outputting, by an electrical component residing in a downhole tool, a clocked digital output. The method also includes adjusting, by a variable impedance circuit external to the electrical component, an impedance value in series with the clocked digital output as a function of temperature.
