Abstract
A design technique that uses nonlinear D/A conversion for low power, area efficient sine output direct digital frequency synthesis (DDFS) is presented. Nonlinear reference voltages are created geometrically and replace the large, power hungry ROM in conventional DDFS circuits. The proposed design is independent of sheet resistance. Finally, design equations and simulations are presented
