A 14-BIT DUAL CURRENT-STEERING DAC (2008)
K. Ola Andersson, Niklas U. Andersson, Mark Vesterbacka, J. Jacob Wikner
A 14-bit dual current-steering digital-to-analog converter implemented in a 0.25 μm CMOS process is presented in this work. Both implementation issues and measurement results are presented. The...
Models and Implementation of a Dynamic Element Matching DAC (2008)
Niklas U. Andersson, K. Ola Andersson, Mark Vesterbacka, J Jacob Wikner
Abstract — The dynamic element matching (DEM) technique for digital-to-analog converters (DACs) has been suggested as a promising method to increase matching between the DAC’s references. However...
A DIFFERENTIAL DAC ARCHITECTURE WITH VARIABLE COMMON-MODE LEVEL (2008)
K. Ola Andersson, Niklas U. Andersson, Mark Vesterbacka, J. Jacob Wikner
A differential current-steering digital-to-analog converter (DAC) architecture allowing the common-mode level of the input signal to be varied is presented. Simulation results with models of...
Understanding Multiplier Design using “Overturned-Stairs ” Adder Trees (2008)
Magnus Karlsson, Oscar Gustafsson, J Jacob Wikner, Thomas Johansson, Weidong Li, Magnus Hörlin, ...
Abstract – Different tree structures are used in high-speed multipliers. One type of trees, the overturned-stairs adder trees of the first order, OS 1 trees, is described in this report. They show...
