Abstract:
This document discusses, among other things, a compensation circuit configured to modulate a control voltage of a switch over a range of ambient temperatures during a conduction state of the switch to maintain a specified resistance between first and second nodes of the switch. The compensation circuit can include a temperature-insensitive resistor configured to provide a sense current, a current mirror configured to provide a mirror current using the sense current, and a temperature-sensitive resistor configured to provide the control voltage using the mirror current.
