Unit cell mismatch scrambling method for high-resolution unary DAC based on virtual 3D layout

[摘要] The paper studies a unit cell mismatch scrambling method for a high-resolution unary DAC based on virtual 3-dimensional (3D) layout, to improve its spurious-free dynamic range (SFDR) for communication applications. This can be implemented with relatively simple interconnections and scrambling circuits, compared to that based on the 2-dimentional (2D) layout.
