Research Abstract
This research investigates the design of ultra-low-power analog circuits for space applications, where energy availability is extremely limited. The goal is to develop key building blocks—such as amplifiers, voltage/current references, and sensor interfaces—capable of operating below 0.5 V with power consumption under 10 nW. The work explores advanced techniques including subthreshold operation, bulk-driven and inverter-based architectures, and forward body biasing, combining them into optimized hybrid solutions. The proposed circuits will be designed, simulated, and experimentally validated on silicon, with the aim of creating a robust and scalable library compatible with standard CMOS technologies for next-generation low-power space systems.
