METHODS AND APPARATUS TO COMPENSATE FOR PACKAGE STRESS VARIANCE OR TEMPERATURE VARIANCE

原文（中国語）

An example apparatus includes a first resistor including a first terminal coupled to a first output terminal of a current mirror and a second terminal coupled to a ground terminal. The apparatus includes a first switch including a first terminal coupled to a second output terminal of the current mirror, a capacitor including a first terminal coupled to a second terminal of the first switch, and a second resistor including a first terminal coupled to a second terminal of the capacitor and a second terminal coupled to the ground terminal. The apparatus includes a second switch including a first terminal coupled to the first terminal of the capacitor and a second terminal coupled to the ground terminal, a third switch including a first terminal coupled to the first terminal of the capacitor, and a comparator including an input terminal coupled to a second terminal of the third switch.
