紀要論文 ノイズシェーピング構成とミスマッチシェーパーを用いたバックグラウンドキャリブレーション型パイプライン ADC

内容記述
We propose a background calibration echnique for a pipeline ADC, which uses an error feedback to realize a band-pass noise shaping and a correlation operation to detect mismatches with a noise shaping dynamic element matching method to realize a high pass mismatch shaping. The detection accuracy and speed can be improved. At the same time, it is possible to realize a noise shaping type pipelined ADC. When the proposed method is applied to a 12-bit pipelined ADC, the simulation results show improvements of 38dB in the SNDR. Key Words : pipelined Analog to Digital Converter,capacitor mismatch,background digital calibration,Noise Shaping Dynamic Element Matching
