The detection can be started at any phase of the input signal. In said mutual-capacitive detection, when a driven conductive strip is being provided with a driving signal, capacitances or changes in capacitances of all intersections on the driven conductive strip are detected with all sensed conductive strips arranged in different dimensions to the driven conductive strip, and are regarded as a row of pixels. When the capacitive pen P approaches or touches an intersection e. In a passive mode, the wire is coupled to DC voltage. If a first voltage variation which exceeds a first threshold is measured by the circuit, it is determined that something is approaching the touch area near the wire.
