Abstract: A signal processing system includes an analog-to-digital converter (ADC) that is used to convert a first analog value into a first digital value and convert a second analog value into a second digital value. The ADC includes a first digital-to-analog converter (DAC) circuit and a second DAC circuit operating in different voltage domains. A first bit segment and a second bit segment of each digital value are determined via the first DAC circuit and the second DAC circuit, respectively. An analog injection value is injected to the second analog value, the analog injection value is converted from a digital injection value formed by a subset of bits of the second bit segment of the first digital value, and the second bit segment of the second digital value is derived from injecting the digital injection value to a digital value determined by the second DAC circuit.

Abstract: A network switch system includes a Power-over-Ethernet (PoE) controller, a power sourcing equipment (PSE) controller, and a host computer. The PoE controller is electrically connected to the PSE controller, and stores a loader and a firmware image. The host computer is connected to the PoE controller and stores a second firmware image. The host computer switches the PoE controller to a firmware upgrade mode when the second firmware image is newer than the firmware image. The PoE controller executes the loader in the firmware upgrade mode and overwrites the firmware image with the second firmware image downloaded from the host computer. The PoE controller checks data integrity of the firmware image with an error detection and correction code included in the firmware image, and restarts if no error is found in the firmware image.
