Abstract:
1. An analog to digital converter (ADC) component comprising: an analog input port that receives an analog input value; a reference voltage input port that receives a reference voltage for the analog input value; a digital input port that receives a digital compare value; a digital output port that provides a digital output value; wherein the ADC component is operable to selectively perform in a conversion mode a conversion action of the analog input value to provide the digital output value, or to perform in a compare mode a compare action of the analog input value against the digital compare value; a capacitor network including a plurality of capacitors, each of the plurality of capacitors being coupled to a respective switch, wherein each respective switch is coupled to the analog input port and the ADC component is operable to charge each of the plurality of capacitors to establish a first voltage at a first input of a comparator by coupling each of the plurality of capacitors to the analog input port, the first voltage having a voltage level that is approximately the same as a voltage level of a second voltage established at a second input of the comparator.
