Talk by Christoph Steffan on 'Monolithic Ultra-Low Power Solar Harvester with High Dynamic MPPT Algorithm' at TUG, Nov 21st 2018
This presentation gives a detailed insight how a standard CMOS process was utilized to fabricate a monolithic solar harvester chip. Possibilities to build on-chip solar cells as well as their performance data are discussed. On the analog circuit side a Dickson charge pump and ultra-low power circuits which evaluate the on-chip produced solar current are shown. A novel method for a continuously operating maximum-power-point-tracking algorithm
(MPPTA) is presented. The presentation contains considerations about the concept, design and layout of the monolithic autonomous chip prototype.
