    摘要: A DA converter circuit is provided for use in a ΔΣ AD modulator. The DA converter circuit includes a DA converter of segment switched capacitor type. The DA converter includes an operational amplifier, capacitors as connected in parallel to each other to supply electric charges to the operational amplifier, an electrically charging switch for switching of electrically charging electric charges onto the respective capacitors or not, and an electrically discharging switch for switching or not electrically discharging electric charges from the respective capacitors or not. A switch device performs either one of the electrically charging, the electrically discharging, grounding, and polarity inversion onto the respective capacitors. A controller controls the electrically charging switch, the electrically discharging switch and the switch device to execute a process of second-order DWA algorithm for performing a second-order noise shaping of a non-linearity of the DA converter circuit.

    摘要: A high-precision ΔΣ modulator reduces nonlinear noise due to the use of a multibit DAC and has little hardware and power consumption. A digital signal is DA converted and fed back to a subtraction circuit supplied with an analog signal. The DAC used in this feedback circuit uses a DAC (DWADAC) that includes a weighted pointer so that input digital signals are supplied in order to a plurality of segment elements that construct the DAC. In this DWADAC, the construction and number of the pointer is set based on the type and order of the filter disposed before the ADC.
