Abstract
An apparatus for sensing power amplifier current includes a system voltage source that is used to develop a reference voltage, a wire bond structure connected between the system voltage source and a power amplifier, where a sense voltage developed across the wire bond structure is indicative of a current flowing through the power amplifier, and a current source configured to compensate the reference voltage for changes in resistance of the wire bond structure due to a temperature coefficient of the wire bond structure.
