Analog and RF circuit performance in single-chip transceivers can severely suffer from coupling of digital switching noise to the silicon substrate. To predict this performance degradation, a deeper understanding of the impact of substrate noise is absolutely necessary. Using measurements, this impact is studied as the cascade of an attenuation through the substrate from the source of substrate...

Voltage boosting from CMOS photovoltaic device (PV) is achieved by implementing multiple PV units on single CMOS chip and are series connected by an external integrated passive device.
