Abstract
A device, for pixel transfer rate boosting, is provided and includes an image sensing array having a plurality of pixel units, in which each of the plurality of pixel units is configured to generate a pixel signal when receiving an electromagnetic energy, a signal buffer circuit, electrically coupled with the image sensing array to receive the pixel signals, a switch circuit electrically coupled with the signal buffer circuit, a capacitor having a first terminal and a second terminal, in which the first terminal electrically couples with the switch circuit and the second terminal connects to a ground, a comparator, electrically coupled with the switch circuit, and a pull-down unit, electrically coupled with the first terminal of the capacitor and the switch circuit. After the switch circuit is turned on, the pull-down unit pulls the plurality of pixel output signals down.
