Abstract: A touch detection device and a method of detecting a touch employ: a current-to-voltage converter configured to convert a reception signal received from a touch panel into a sensing signal, and further configured to be periodically reset for a first time period in response to a reset signal; a digital-to-analog converter configured to convert an analog signal based on the sensing signal into a first digital output signal, and a controller configured to generate a second digital output signal based on the first digital output signal by performing data interpolation on a first portion of the first digital output signal corresponding to the first time period.
