Abstract—This paper describes the architecture and the IC implementation of a direct digital frequency synthesizer (DDFS) that is based on an angle rotation algorithm (similar to CORDIC). It is shown that the architecture can be implemented as a mul
转载关于WIFI 2.4G上20_40MHz带宽的一篇文章; Abstract—We investigate the impact of 20/40 MHz coexistence on the performance of wireless local area networks(WLANs). To that end, we present simulation results of overlapping basic service sets (BSSs), a 802.11n BSS
1. 6 MHz 降压型 DC - DC 转换器中的斜率补偿设计pdf,PWM 电流模控制方式在 DC - DC 转换器设计电路中得到了广泛应用,也带来了斜率补偿问题。讨论了降压型 DC - DC 转换器中斜率补偿技术的原理,分析了传统的线性补偿技术并详细介绍了一种改进的分段线性补偿电路,给出了在1. 6 M Hz 降压转换器中的实际应用电路。电路基于 CSMC 0. 5μm CMOS 工艺设计,通过 Cadence Spectre 仿真验证,该斜坡补偿电路有效解决了子谐波振荡以及过补偿问题。
