loop bandwidth中文什么意思
例句与用法
- since commercial pll ic came out, phase-locked-loop frequency synthesis has become widely accepted . but when narrow frequency-step is required, the loop bandwidth has to decrease while cannot meet the demand of frequency-hopping speed
数字锁相集成器件出现以来,锁相式频率合成器得到迅速发展,但是当需要窄频率步进时,环路带宽需要降低,致使锁定时间变长,不能满足快速跳频的要求。 - contrapose to the instability of the third-order charge-pump pll system, the loop optimization method is employed in system level design to decide the bandwidth and phase margin, therefore the loop bandwidth locates at the maximum phase margin to guarantee the stability of the system . according to tsmc 0.35 m sige bicmos model, the sub-circuits in the designed pll and the whole system are simulated and verified by the cadence spectre
5.根据tsmc0.35msigebicmos工艺模型,利用cadencespectre模拟软件对所设计的电荷泵锁相环路中各个模块及整个系统进行了模拟仿真,模拟结果显示,在1.5v电源电压下,频率为200mhz的参考输入信号,输出中心频率为800mhz,分频电路采用4分频,环路带宽为10mhz,捕获时间大约为0.92s,功耗大约为15mw,达到了设计指标。
