A direct current (“DC”) calibration reference voltage is applied at an input terminal of an N-level sigma-delta analog-to-digital converter (“ADC”). The ADC includes a current-mode DAC (“I-DAC”) operating as a feedback element. A count of logical 1s associated with each of N output levels is taken at outputs of a modulator portion of the ADC during a first mismatch measurement interval. Mismatch measurement logic subsequently transposes pairs of current sources between level selection switch matrices. Doing so causes modulator output error components resulting from mismatches between I-DAC current sources (“delta”) to appear as differential level-specific output counts. The mismatch measurement logic compares the differential counts to determine values of delta. The ADC then factors decimated modulator output counts by values of delta in order to correct for the I-DAC current source mismatch(es). |

Dual band antenna pair with high isolation
A dual band printed antenna pair operates simultaneously at both WLAN frequency bands (2.4 GHz/5 GHz). The antenna pair provides high isolation between both antennas while having an efficient over the air performance. The antenna pair achieve greater than 20 dB isolation at 2.4 GHz and 5 GHz band, while having antennas positioned in close proximity. The high isolation is accomplished using an orthogonal antenna configuration (exploiting orthogonal polarization) and a parasitic element to further enhance isolation at 2.4 GHz. The antenna pair and parasitic element are printed on a Printed Circuit Board (PCB) adding relatively little cost to the Radio Frequency (RF) interface. The PCB is then fixed on top of a metal chassis with the antenna keep out area overhanging a corner of the metal chassis to enhance performance. |

Method for cooling a lithium-ion battery pack
Systems are disclosed for battery modules with cooling systems. In accordance with disclosed embodiments, the cooling system may be disposed against an external surface of a housing of the battery module. The cooling system may utilize a coolant to remove heat generated by cells within the battery module, to prevent the cells from aging prematurely. Embodiments of the cooling system may include cold plates, tubes, fins, and plates, or a combination thereof, which may route the coolant along the surface of the battery module housing. Such features may create a large effective cooling surface against the battery module housing to promote a high heat transfer rate from the cells to the coolant. |
