摘要:
A switch-capacitor (“SC”) amplifier includes a two-stage operational amplifier (“OP-AMP”), an input SC network, and a feedback SC network. The two-stage OP-AMP includes a first OP-AMP stage having an output coupled to an input of a second OP-AMP stage. The input SC network is coupled to an input of the first OP-AMP stage. The feedback SC network is configured to selectively couple the output of the first OP-AMP stage to the input of the first OP-AMP stage during a first phase of operation of the scamplifier and to couple an output of the second OP-AMP stage to the input of the first OP-AMP stage during a second phase of operation of the SC amplifier.
摘要:
An analog-to-digital converter based on an interleaving architecture is disclosed. The analog-to-digital converter can include a first sample and hold circuit for sampling and temporarily storing a first input signal. The analog-to-digital converter can also include a comparator for converting the sampled first input signal into a digital signal in a first time period. The analog-to-digital converter can further include a second sample and hold circuit for sampling and temporarily storing a second input signal in a second time period. The second time period at least partially overlaps with the first time period.
