Abstract

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.
