概要

• 論文の詳細を見る

• This work describes an 8b 240MS/s CMOS ADC as one of embedded core circuits for high-performance displays based on low-noise on-chip references and dual-mode inputs with the requirements of limited pins, low power, and small size at high speed. The proposed ADC uses externally connected pins only for analog inputs, digital outputs, and supplies. The ADC employs (1) a two-step pipeline architecture to optimize power and chip size at the target sampling frequency of 240MHz, (2) advanced bootstrapping techniques to achieve high signal bandwidth in the input SHA, and (3) RC filter-based on-chip current and voltage references to improve noise performance with a power-off function for portable applications. The prototype ADC is implemented in a 0.18μm CMOS and simultaneously integrated in a DVD system with dual-mode inputs. The prototype ADC shows the measured DNL and INL within 0.49LSB and 0.69LSB, and the SNDR and SFDR exceeding 38dB and 50dB for inputs up to the Nyquist frequency at 240MS/s. The ADC consumes 104mW at 240MS/s and an active die area is 1.36mm^2.
