摘要

This paper presents a wideband linear direct-digital RF modulator (DDRM) in 40-nm CMOS technology. An innovative I/ Q-interleaving RF digital-to-analog converter (DAC) is proposed to enable the combination of in-phase (I) and quadrature (Q) signals in a more digital fashion, thereby improving the linearity performance at large bandwidths. The DDRM also features an advanced second-order hold digita...
