Abstract
A summing circuit, including a capacitor, a switching circuit capable of connecting the capacitor between a first node (ana) and a second node (ref), between a third node and the second node in a first connection direction or between the third node and the second node in a second connection direction, an integrator coupled to the third node, a hysteresis comparator coupled to the output of the integrator, and a counter coupled to the output of the hysteresis comparator.
Claims13
A summing circuit comprising:
- a capacitor comprising first and second plates;
- a switching circuit capable of connecting the capacitor according to a first, a second, or a third configuration, the first plate being connected to a first node, the second plate being connected to a second node and the first and second plates not being connected to a third node in the first configuration, the first plate being connected to the third node, the second plate being connected to the second node and the first and second plates not being connected to the first node in the second configuration and the second plate being connected to the third node, the first plate being connected to the second node and the first and second plates not being connected to the first node in the third configuration;
- an integrator coupled to the third node;
- a hysteresis comparator coupled to the output of the integrator;
- and
- a counter coupled to the output of the hysteresis comparator.
