This chip advances Pipistrelle-1’s design, taking another step towards filling in the pieces required to build an autonomous minimum-energy sensor system. Low power clock sources are an important part of a minimum energy system for driving CPUs, switched-capacitor converters, power-management unit logic, wake-up timers and more. This chip takes the first step to prototyping suitable fully-integrated oscillator topologies, as well as improving on previous versions of SRAM, power and energy harvesting converters.
