A circuit for generating reference voltages for an A/D converter is presented. The circuit consisting of a bandgap reference and a driver circuit is capable of operating on sub 1-volt supply voltages. The circuit is designed using a standard 0.5 m CMOS technology. Simulations show maximum 0.24% variation in the generated reference voltage over a temperature range from -20 C to 100C and a supply...

Present distribution grids generally have limited sensing capabilities and are therefore characterized by low observability. Improved observability is a prerequisite for increasing the hosting capacity of distributed energy resources such as solar photovoltaics (PV) in grids. In this context, paper presents learning-aided low-voltage estimation using untapped but readily available widely sensor...
