该论文提出了一种15位正交数字功率放大器，采用基于变压器的复数域功率效率增强技术。解决了传统数字功率放大器在效率与分辨率之间的折衷问题，实现了高分辨率与高效率的融合。
law to provide compact die area, better interface to digital back-end, and higher power efficiency due to the faster switching nature of core devices even in face of reduced supply voltages. Moreover, the integration of high-power high-efficiency digital power amplifiers (DPAs) on-chip is highly desired for cost reduction, longer battery life, and fast time to market. Recently, digital polar and quadrature TXs have become very attractive architectures [1-7]. Compared with polar TXs, quadrature TXs do not need CORDIC, phase modulators, or time-synchronization circuits, showing good compatibility with wideband communication systems, but the I/Q combination limits the output power and efficiency. To support most wideband applications while enhancing the power efficiency, several techniques
