| Abstract: | In this paper, a high resolution dual-slope integrating analog-to-digital converter was researched by using the tech- nology of 0.18urn COMS. By means of the theoretical analysis and experimental simulation, a 16-bit A/D conversion circuit with the accuracy of 0.5% was constructed. The conversion cycle of this A/D conversion circuit is 109ms in the clock frequency of 1 MHz. The simulation results of the A/D converter were given and analyzed to demonstrate its feasibility, merits and demerits. |
