Low-Power Low-Voltage Sigma-Delta Modulators in Nanometer CMOS
addresses the low-power low-voltage Sigma-Delta ADC design in nanometer
CMOS technologies at both the circuit-level and the system level.
The low-power low-voltage Sigma-Delta modulator design at the circuit
level is introduced. A design example is presented in this book. This
design is the first published Sigma-Delta design in a 90-nm CMOS
technology and reaches a very high figure-of-merit.
At the system level, a novel systematic study on the full feedforward
Sigma-Delta topology is presented in this book. As a design example, a
fourth-order single-loop full feedforward Sigma-Delta modulator design
in a 130-nm pure digital CMOS technology is presented. This design is
the first design using the full feedforward Sigma-Delta topology and
reaches the highest conversion speed among all the 1-V Sigma-Delta
modulators to date.
