Abstract(in English) | In recent years, C-DAC (Capacitor Digital to Analog Converter) is often used as a reference voltage source in a successive approximation ADC (Analog to Digital Converter). In general, a C-DAC consists of a MOS switch and a group of capacitors with binary weighted capacitance values. However, the parasitic capacitance that causes an error in the capacitance ratio, and therefore it is necessary to readjust the capacitors’ value one by one from the simulation results. In this study, we analyze the relationship between the W/L ratio of the MOS switch and the capacitance ratio after the adjustment. And then by calculating the coefficient of the relationship, the comprehensive adjustment method of the C-DAC capacitance ratio that considers the parasitic component of the MOS switch will be examined. |
