A fully-integrated DC/DC converter for energy harvesting applications is presented. The startup-voltage of the converter is about 140mV, the output voltage exceeds 1.5V, with a power efficiency at least 20%. The architecture for boosting such extremely low voltages is based on an ultra-low-voltage oscillator cross connected to two phase charge pump. The(More)
With the increasing use of low voltage portable devices, analog circuits with low power consumption and ultra low voltage supply are needed. In this circuits the susceptibility to electromagnetic interferences has not deeply investigated. In this paper, the effects of interferences in an ultra low voltage CMOS amplifier designed to have high EMI immunity(More)
