Abstract

PURPOSE:To decrease the time for a conversion process for a D/A converter using distribution and transfer of electric charge, by giving a converting process to an input signal after dividing it into several parts. CONSTITUTION:Electric charge distributing circuits 11 and 12 plus an integrator 14 are used in accordance with the divided bit groups in order to give a converting process to a digital input signal of N bits after dividing it into several parts. Capacitors C11, C12, C14 and C15 are weighted with each of the circuits 11 and 12. With this weighting, each bit group can perform simultaneously the distribution, transfer and discharging of the electric charge in response to the digital input signal of each bit group. Thus the digital input signals of N bits are processed at one time, and the electric charges given from the circuits 11 and 12 are superposed on an integrating capacitor C13 of an integrator 14 to obtain a digital input signal of N bits.
