Sense circuit with sample capacitors and switch set for adjustable voltage sampling

A system, comprising:

• a first resistor coupled between a resistor terminal and a ground terminal;
• a second resistor coupled between a voltage terminal and the resistor terminal;
• a first capacitor having a first capacitor terminal and a second capacitor terminal;
• a second capacitor having a third capacitor terminal and a fourth capacitor terminal;
• a first switch coupled between the voltage terminal and the first capacitor terminal;
• a second switch coupled between the ground terminal and the first capacitor terminal;
• a third switch coupled between the voltage terminal and the third capacitor terminal;
• a fourth switch coupled between the resister terminal and the third capacitor terminal;
• a fifth switch coupled between the ground terminal and the third capacitor terminal;
• and
• a comparator having a comparator output and first and second comparator inputs, the first comparator input coupled to the second and fourth capacitor terminals.
