  • Patent number: 12003249
    Abstract: The present invention discloses a DAC method having signal calibration mechanism used in a DAC circuit having thermometer-controlled current sources generating an output analog signal according to a total current thereof and a control circuit. Current offset values of the current sources are retrieved. The current offset values are sorted to generate a turn-on order, in which the current offset values are separated into current offset groups according to the turn-on order, the signs of each neighboring two groups being opposite such that the current offset values cancel each other when the current sources turn on according to the turn-on order to keep an absolute value of a total offset not larger than a half of a largest absolute value of the current offset values. The current sources are turned on based on the turn-on order according to a thermal code included in an input digital signal.

  • Publication number: 20240164043
    Abstract: A swivel bracket assembly and a method for installing an electrical component to a riser bracket assembly are disclosed. The swivel bracket assembly includes a baseplate; a swivel bracket rotatably attached to the baseplate, the swivel bracket being rotatable between an open position and a closed position; and pads attached to the swivel bracket, at least one of the pads being configured to contact and support the electrical component attached to the riser bracket assembly when the swivel bracket is in the closed position. A method for installing an electrical component to a riser bracket assembly includes receiving the electrical component into a slot of a riser circuit board and pivoting a swivel bracket rotatable coupled to a baseplate from an open position to a closed position to support the electrical component secured to the riser bracket assembly.

  • Publication number: 20240154447
    Abstract: A power system including a first battery pack, a second battery pack, and a power management circuit is disclosed. The first battery pack has a first end and a second end, and has a first battery capacity. The second battery pack has a third end and a fourth end. The third end is coupled to the second end of the first battery pack and provides a low battery voltage. The fourth end is grounded, the second battery pack has a second battery capacity, and the second battery capacity is greater than the first battery capacity. The power management circuit is coupled to the second battery pack to receive the low battery voltage, and provides a component operating voltage to an electronic components based on the low battery voltage.
