A noise-shaped pipelined ADC is presented in this paper. A minimal complexity ΔΣ modulator in
the first two sub-ADCs and residue feedback in the latter stages lead to high-order noise shaping. This
also leads to reduced sensitivity to analog imperfections in the front-end stage. Implemented in 0.18μ m
CMOS, the...
Advances in electronic systems have lead to the demand for high resolution, high bandwidth Analog-to-Digital Converters (ADCs). Oversampled ADCs are well- known for high accuracy applications since they benefit from noise shaping and they usually do not need highly accurate components. However, as a consequence of oversampling, they have limited...
