Abstract

Cognitive analysis using applied analog circuits including receiving, by a circuit, a first set of data results and a second set of data results; charging a first capacitor on the circuit with a first unit of charge for each of the first set of data results that indicates a positive data point; charging a second capacitor on the circuit with a second unit of charge for each of the second set of data results that indicates a positive data point; applying a charge from the first capacitor and a charge from the second capacitor to an analog unit of the circuit; and generating a signal on a circuit output indicating that a ratio of the positive data points in the first set of data results to the positive data points in the second set of data results is greater than a statistical significance.

First claim

What is claimed is:

receiving, by a circuit, a first set of data results and a second set of data results, wherein each set of data results comprises binary data points;
charging a first capacitor on the circuit with a first unit of charge for each of the first set of data results that indicates a positive data point;
charging a second capacitor on the circuit with a second unit of charge for each of the second set of data results that indicates a positive data point;
applying a charge from the first capacitor and a charge from the second capacitor to an analog unit of the circuit, wherein the analog unit generates a signal on an analog unit output indicating a difference between the charge on the first capacitor and the charge on the second capacitor;
determining, by the circuit based on the analog unit output, that the difference between the charge on the first capacitor and the charge on the second capacitor is greater than a threshold number of units of charge; and
generating a signal on a circuit output indicating that a ratio of the positive data points in the first set of data results to the positive data points in the second set of data results indicates a degree of certainty that positive data points in one set of data results occur more frequently than positive data points in the other set of data results, wherein the signal on the circuit output is at least based on the analog unit output.

2. The apparatus of claim 1 , wherein the analog unit comprises:
a first differential amplifier configured to receive the charge from the first capacitor; and
a second differential amplifier configured to receive the charge from the second capacitor.

3. The apparatus of claim 2 , wherein the analog unit further comprises a plurality of resistors, wherein each of the plurality of resistors have equivalent resistance.

4. The apparatus of claim 1 , wherein the statistically significant threshold number of units of charge is calculated as a function of a ratio, a probability range, and a confidence level.

5. The apparatus of claim 1 , wherein the first capacitor and the second capacitor are charged to a baseline charge before being charged with the units of charge.

6. The apparatus of claim 1 , the circuit further configured to carry out the steps of:
determining that the charge on the first capacitor has exceeded a capacitor threshold; and
resetting the charge on the first capacitor and the second capacitor to a baseline charge.

7.
