发明名称 タッチパネルの制御回路およびそれを用いたタッチパネル入力装置、電子機器
摘要 <p>A voltage generating unit includes an output transistor arranged as a first-terminal side extension of a path that includes a first terminal, a first resistive film, and a second terminal, and is configured to apply a first bias voltage to the first terminal. A current detection unit includes a detection transistor connected to the output transistor such that they form a current mirror circuit, a detection resistor arranged on a path of the detection transistor, and an amplifier circuit configured to amplify the difference between a voltage drop across a detection resistor and a predetermined voltage, and to output the difference thus amplified as a value which represents a panel current.</p>
