The coplanar double lap-joint is the weld type mainly used for the connection of skin and stringer. The welding deformation in the component will reduce fabrication accuracy and bearing capacity and the excessive welding deformation can even render t

A 12-bit nonlinear digital-to-analog converter (DAC) was fabricated in a 0.35-mum SOI CMOS process. The nonlinear DAC can implement a piecewise-linear approximation to a sine function and results in significant reduction of complexity and power dissi

A radiation hardened direct digital frequency synthesizer (DDFS) was designed in 0.18 mum CMOS technology. A novel 14-bit nonlinear DAC is used to generate sine waves using a piecewise quadratic approximation. The nonlinear DAC effectively reduces lo

A technique to reduce ROM size and therefore power dissipation in direct digital frequency synthesizers (DDFS) is to use a non-linear DAC to approximate the sine function. Piecewise-linear and piecewise-quadratic approximations were investigated for
