Abstract: Systems and methods are related to a successive approximation analog to digital converter (SAR ADC). The SAR ADC includes a sample and digital to analog conversion (DAC) circuit configured to sample an input voltage, a comparator circuit coupled to the sample and DAC circuit and having an output, a first set of storage circuits, and a comparator driver. The comparator driver is disposed between the output and the first set of storage circuits (e.g., ratioed latched. The first set of storage circuits are coupled to the comparator circuit and the sample and DAC circuit. The comparator driver can include a first driver and second driver. The first driver is coupled to a first input of a first storage circuit of the first set of storage circuits, and the second driver is coupled to first inputs of a second set of storage circuits within the first set of storage circuits.

Abstract: Systems and methods are related to a successive approximation analog to digital converter (SAR ADC). In one aspect, a method includes sampling, by a sample and digital to analog conversion (DAC) circuit, an input voltage to obtain a sampled voltage. The method also includes determining, by a comparator coupled to a set of storage circuits, a state of a plurality of bits corresponding to the sampled voltage. The comparator has a current parameter or voltage parameter adjusted based upon a conversion margin. Adjustment of the current parameter or the voltage parameter affects speed of determining the state of the bits. The method also includes storing the bits in the set of storage circuits. In some aspects, an SAR ADC is configured to perform the method.

Abstract: Wave energy conversion (WEC) systems and methods for harvesting wave energy by use of the systems are described. WEC systems incorporate a plurality of submerged oscillating water columns (SOWC) that encourage oscillating water motion within each submerged column to mimic the motion of waves passing the SOWC system. A WEC system includes multiple SOWC connected to one another via air pockets within each submerged column. Each SOWC includes a float connected to a power take-off. The oscillations of the floats are converted to useful energy by the power take-off of the system.
