Abstract:
PURPOSE: An analog-to-digital converter circuit and an integration circuit including the same are provided to adjust the frequency of a clock signal and the resolution while in use. CONSTITUTION: An analog-to-digital converter circuit (10A) includes a first comparing circuit (100), a second comparing circuit (200), and a selecting circuit (300). The first comparing circuit compares the first analog signal related to a first digital signal and the analog input signal and according to the comparison result, outputs a first selection signal. The second comparing circuit compares the second analog signal related to a second digital signal and the analog input signal and according to the comparison result, outputs a second selection signal. The selecting circuit generates intermediate digital signals related to the first digital signal and outputs one among the intermediate digital signals as a first digital signal and another one as a second digital signal, based on the first selection signal and the second selection signal.
Abstract:
An LED driving system according to one embodiment of the present invention includes: an LED array which includes a plurality of LEDs which are connected to one bus; a monitoring unit which monitors the failures of the LEDs to specify an LED with the failure; and a driver which drives the LED array based on a monitoring result received from the monitoring unit.
