Research Abstract |
This research is about the development complex AD converter circuits for the applications to RF receivers in wireless communication systems. We proposed new architectures of AD converter, and the higher performance can be realized just by adding some passive capacitors and switches, the additional analog circuits composed of an operational amplifier is not necessary, and the performance of the AD converter can be effectively raised without additional power dissipation. MATLAB and SPICE simulation results show the effectiveness of the proposed architectures. LSI chips are also fabricated to confirm the validity of the proposed architectures.
