通过频率锁定环实现精确随机频率合成的电路
A circuit for precise random frequency synthesis via a frequency locked loop
摘要:
频率合成(FS)是一种对各种射频(RF)通信至关重要的技术,例如:移动电话,蓝牙,Wi-Fi,收音机,电视和卫星,以及其他需要稳定和可编程频率的周期性信号的设备。在这项工作中,我们提出了一个推广的FS技术的随机,非周期性信号,其主要用途是在新的领域的随机神经形态计算,信息安全和仪器。由于传统的FS电路不能与随机信号一起工作,我们引入了一种新的随机频率比检测器,它可以与随机信号和周期信号一起工作。
英文摘要:
Frequency synthesis (FS) is a technique vital for all kinds of radio frequency (RF) communications, such as: mobile phones, Bluetooth, Wi-Fi, radio, TV and satellite, and in other equipment requiring periodic signals of stable and programmable frequency. In this work, we present a generalization of the FS technique to random, non-periodic signals, whose main use is in the new area of stochastic neuromorphic computing and, information security and instrumentation. Since conventional FS circuits cannot work with random signals, we introduce a novel random frequency ratio detector, that works both with random and periodic signals.
