Converting integrator, touch driving circuit, and touch display device

A touch display device, comprising:

• a plurality of touch electrodes disposed on or in a display panel;
• and
• a touch driving circuit configured to drive the plurality of touch electrodes by outputting a touch driving signal having a first level period and a second level period,
• wherein the touch driving circuit includes:
• a current regulator configured to:
• receive an input current from at least one of the plurality of touch electrodes during at least a partial period of the first level period and at least a partial period of the second level period of the touch driving signal, and
• scale down the input current to a first current and output the first current;
• and
• a converting integrator configured to:
• output a sensing voltage based on the first current or a second current adjusted from the first current, and
• wherein the touch driving circuit further includes:
• a first charge regulator electrically connected to an input end of the current regulator, and configured to adjust a charge amount of the input current based on a capacitance adjustment;
• and
• a second charge regulator electrically connected between the current regulator and the converting integrator, and configured to output the second current based on adjusting a charge amount of the first current based on a current adjustment.

A touch driving circuit, comprising:

• a current regulator configured to:
• receive an input current from a touch electrode to which a touch driving signal having a first level period and a second level period is applied, and
• output a corrected current produced by scaling down the input current;
• and
• a converting integrator configured to:
• receive the corrected current from the current regulator, and
• output a sensing voltage by integrating a voltage based on the corrected current in each of the first level period and the second level period of the touch driving signal,
• wherein the current regulator further includes a power domain shifter electrically connected to an input end of the converting integrator the current regulator being configured to convert the first current from a current in a high voltage range to a current in a low voltage range.
