Design of On-Chip Readout Circuitry for Spin-Wave Devices

We present the design of readout circuitry based on complementary metal-oxide semiconductors (CMOS) for spin-waves. The circuit provides the functionality of a high-speed oscilloscope/spectrum analyzer, and can be integrated with a spin-wave-based signal processing device. The circuit consumes sub-50 mW power and requires an area below 1 mm

. A spin-wave-based processing system, when combined with the presented electrical input/output circuitry, can perform complex microwave signal processing tasks, with speed, power consumption, and area that are not feasible in a CMOS-only system.
