In described examples of a method and circuit for sensing current, a first current (Ir) flows through a first capacitor (108). A second capacitor (220) is coupled to the first capacitor (108) to form a current divider. A second current (Is) flows through the second capacitor (220) and is proportional to the first current (Ir). A transimpedance amplifier (240) is coupled to an output of the second capacitor (220) and has a voltage output (VO) that is proportional to the second current (Is). |
