Abstract
Official abstract text for this publication.
A direct conversion receiver includes: a high linearity mixer device including a sampler unit charge-sampling an input current according to a sampling frequency, and a buffer unit receiving an output signal from the sampler unit while having a low input impedance, amplifying the received signal, and outputting a current signal; and a filter device decimating an output signal from the mixer device and FIR-filtering the decimated signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A decimation filter for filtering a positive signal and a negative signal output from a mixer device, the decimation filter comprising: four banks performing an operation of a sampling mode to charge electric charges and an operation of a charge sharing mode to output the charges charged in the sampling mode, wherein the four banks include: a bank Ap connected to the positive signal output from the mixer device and performing the operation of the samplin…
