采用0.18/spl mu/mCMOS工艺的1.8V折叠内插模数转换器采用小尺寸器件实现了超过1.6GS/s的转换速率。固有失配失调经过透明校准,在1.6GS/s时,ADC可实现0.15LSB DNL、0.35LSB INL、7.5 ENOB(100 MHz输入)和7.26 ENOB(奈奎斯特)。
A 1.8V folding-interpolating ADC in 0.18/spl mu/m CMOS uses small device sizes to achieve a conversion rate exceeding 1.6GS/s. The inherent mismatch offsets are calibrated transparently, and at 1.6GS/s the ADC achieves 0.15LSB DNL, 0.35LSB INL, 7.5 ENOB at 100MHz input, and 7.26 ENOB at Nyquist.
