Analog-to-digital converters are critically important in electronic systems. The
difficulty in meeting high performance parameters increases as integrated circuit design
process technologies advance into the deep nanometer region. Sigma-delta analog-todigital
converters are an attractive option to fulfill many data converter requirements.
These data converters offer high performance while relaxing requirements on the precision
of components within an integrated circuit. Despite this, the active integrators found within
sigma-delta analog-to-digital converters present two main challenges. These challenges are
the power consumption of the active amplifier and achieving gain-bandwidth necessary for
sigma-delta data converters in deep nanometer process technologies. Both of these
challenges …
Analysis And Design Of Low Power Cmos Ultra Wideband Receiver, Abdul Bhuiyan
Analysis And Design Of Low Power Cmos Ultra Wideband Receiver, Abdul Bhuiyan
UNLV Theses, Dissertations, Professional Papers, and Capstones
This research concentrates on the design and analysis of low power ultra wideband receivers for Multiband Orthogonal Frequency Division Multiplexing systems. Low power design entails different performance tradeoffs, which are analyzed. Relationship among power consumption, achievable noise figure and linearity performance including distortion products (cross-modulation, inter-modulation and harmonic distortion) are derived. From these relationships, circuit design proceeds with allocation of gain among different sub circuit blocks for power optimum system.
A power optimum RF receiver front-end for MB-OFDM based UWB systems is designed that covers all the MB-OFDM spectrum between 3.1 GHZ to 9.6 GHZ. The receiver consists of a …
