摘要： An analog-to-digital converter includes a successive approximation converter, a voltage comparator, and a controller. The successive approximation converter receives an analog input voltage and a first reference voltage, determines the level of a voltage of a first node as a negative level of the analog input voltage, and using a successive approximation method determines an output logic value corresponding to one bit of the N-bit output digital code at every one successive approximation cycle while adjusting the level of the voltage of the first node based on a level of the first reference voltage. The voltage comparator compares the level of the voltage of the first node with a level of a second reference voltage to generate a comparison logic value. When the output logic value or the comparison logic value satisfies a condition, the controller terminates conversion and determines the N-bit output digital code.

摘要： A display apparatus includes a display panel; a touch sensing unit (TSU) on the display panel and including first and second transmission touch lines (TTL); and a touch driving circuit (TDC). The TDC applies first and second touch driving signals (TDS) to the first and second TTL, respectively. The TDC includes first and second sharing switch devices (SSD) respectively connected to the first and second TTL. The first and second SSD are connected to each other. The first TDS has a first voltage level during a first period, and the second TDS has a second voltage level different than the first voltage level during the first period. The TDC is configured to turn on the first and second SSD during a second period after the first period such that the first and second TDSs have a voltage level between the first voltage level and the second voltage level.
