摘要

我们提出了第一个65nm CMOS连续时间混合计算单元，能够求解四阶非线性微分方程，并可扩展到更高阶。这些方程中使用的任意非线性函数由可编程无时钟连续时间8b混合架构(ADC+SRAM+DAC)实现，该架构具有与活动相关的功耗。我们还演示了该单元在低功耗网络物理系统应用中的使用。

Continuous-time hybrid computation with programmable nonlinearities

We present the first continuous-time hybrid computing unit in 65nm CMOS, capable of solving nonlinear differential equations up to 4th order, and scalable to higher orders. Arbitrary nonlinear functions used in such equations are implemented by a programmable clockless continuous-time 8b hybrid architecture (ADC+SRAM+DAC) with activity-dependent power dissipation. We also demonstrate the use of the unit in a low-power cyber-physical systems application.
