Abstract (in Japanese) (See Japanese page) 
(in English) We have proposed the method of re-measuring quantizing error of Single-Slope ADC for CMOS imager with TDC (Time-to-Digital Converter). Using n-bits TDC, the proposed ADC performed 2n time faster operation. This method requires high-speed Ramp wave generation. Therefore, in this paper, we evaluated speed up with interleave operation and output summing of DACs. Although multiple DACs are used, there is no increase of quantization unit devices. In the interleaved DAC with 2n-m of m-bits DAC units, it can perform as a Delta DAC (-2l≦Vout≦2m-l). We designed fabricated the current-controlled DAC circuits using 0.18um CMOS process. At 100-MHz-clock operation, we confirmed 400-MHz 12-bit operations with four of 10-bits DAC units. The circuit was able to achieve DNL of +0.5/–0.5 LSB and INL of +0.7/–0.8 LSB. The entire generator consumed 5.58 mW with a 1.8-V supply.
