| Abstract(in English) | We propose an area reduction method of digital circuit part in analog-to-digital converter (ADC) based on β-expansion. The digital parts of existing β-expansion based ADCs uses lookup tables (LUTs) to estimate effective β values and to convert non-binary numbers to binary numbers. Unfortunately, increasing the conversion precision of the ADCs increases the area of the LUTs. In this work, in order to eliminate the LUTs, we estimate the effective β values by Newton’s method and directly convert non-binary numbers to binary numbers. When the conversion precision of the ADCs is increased, the proposed method reduces the increase of the digital part area compared to the existing LUT-based method. |
