In conventional communications systems, information is transmitted by modulating the frequency, amplitude or phase of the carrier signal, which often occurs in a binary fashion over a very narrow bandwidth. Recently, ultra-wideband signal transmission has gained interest for local communications in technologies such as autonomous local sensor networks and on-chip communications, which presents a challenge for conventional electronics. Spin-torque nano-oscillators (STNOs) have been studied as a potentially low power highly tunable frequency source, and in this report we expand on this to show how a specific dynamic phase present in vortex-based STNOs makes them also well suited as Wideband Analogue Dynamic Sensors (WADS). This multi-functionality of the STNOs is the basis of a new modulation and demodulation scheme, where nominally identical devices can be used to transmit information in both a digital or analogue manner, with the potential to allow the highly efficient transmittance of data.

在传统的通信系统中，信息是通过调制载波信号的频率、幅度或相位来传输的，这通常在非常窄的带宽上以二进制方式发生。最近，超宽带信号传输在自主本地传感器网络和片上通信等技术中引起了本地通信的兴趣，这对传统电子产品提出了挑战。自旋扭矩纳米振荡器 (STNO) 已作为一种潜在的低功耗高度可调谐频率源进行了研究，在本报告中，我们对此进行了扩展，以展示基于涡旋的 STNO 中存在的特定动态相位如何使它们也非常适合用作宽带模拟动态传感器 (WADS)。 STNO 的这种多功能性是新调制和解调方案的基础，其中名义上相同的设备可用于以数字或模拟方式传输信息，并有可能实现高效的数据传输。
