Abstract
There is a voltage dividing circuit having a voltage dividing resistor for generating reference voltages for A/D conversion. The voltage dividing resistor further comprises a semiconductor element and, provided thereon, a resistance element, at least one capacity electrode and dielectric held therebetween. Each capacity electrode thereon is earthed. The voltage dividing resistor and the voltage dividing circuit are capable of lowering impedance of output terminals in a high frequency range, while avoiding an increase of a surface area of a chip, and undulation of impedances of output terminals in a high frequency range.
