摘要： An analog-to-digital converter (ADC) circuit comprising two time-interleaved successive approximation register (SAR) ADCs. Each of the two time-interleaved SAR ADCs comprises a first stage SAR sub-ADC, a residue amplifier, a second stage SAR sub-ADC and a digital error correction logic. The residue amplifier is shared between the time-interleaved paths, has a reduced gain and operates in sub-threshold to achieve power effective design.

摘要： A reconfigurable receiver, a reconfigurable transmitter and a multimode receiver are disclosed, operating in accordance with a two-step channel selection. In the receiver, the first step provides for a coarse radio frequency (RF) channel selection, to downconvert a desired channel and an image channel of the desired channel to IF. The second step provides for a fine intermediate frequency (IF) channel selection to select either the desired channel or the image channel. In the transmitter, the first step provides for a fine channel selection and upconversion of a desired channel to either positive or negative IF. The second step is a coarse channel selection and upconversion of a desired channel to the RF. The receiver and transmitter can be used in a transceiver.
