This paper presents a column-level 14-bit two-stage analog-to-digital converter (ADC) based on pseudo-differential operational amplifier, which is designed for the readout circuit of X-ray sensor array. This low-power hybrid ADC employs an incremental sigma-delta ADC and a cyclic ADC, achieving a good trade-off between accuracy and conversion speed. The two stages share the same analog circuit to...
This paper presents a low-power 14-bit hybrid incremental Σ-Δ/cyclic analog-to-digital converter (ADC) based on pseudo-differential operational amplifier, which is designed for the readout circuit of infrared focal plane array detector. This two-stage hybrid ADC employs an incremental sigma-delta ADC and a cyclic ADC, achieving a good trade-off between accuracy and conversion speed. The two stages...
