TL;DR: In this article, a simple model of a linear voltage regulator circuit, which is suitable to investigate the propagation of EMI through integrated circuit power distribution networks is proposed and it is validated by comparison of model predictions, computer simulations and experimental results.
Abstract: In this paper, a simple model of a linear voltage regulator circuit, which is suitable to investigate the propagation of EMI through integrated circuit power distribution networks is proposed and it is validated by comparison of model predictions, computer simulations and experimental results. Moreover, application examples of the new model in EMC analysis are given with reference to both susceptibility and emission issues.

TL;DR: A compact, very low voltage, temperature-independent reference circuit, which is based on the thermal properties of bipolar junction transistors in the saturation region is presented and provides a reference voltage with a nominal thermal drift in the temperature range between −40 and 110°C.
Abstract: A compact, very low voltage, temperature-independent reference circuit, which is based on the thermal properties of bipolar junction transistors in the saturation region is presented. The new circuit operates from a minimum power supply of less than 1V and provides a reference voltage with a nominal thermal drift of ∼30 ppm/°C in the temperature range between −40 and 110°C. The proposed circuit has been integrated on silicon by a 0.35 µm CMOS technology and a reference voltage with a measured untrimmed thermal drift of ∼100 ppm/°C has been reported. The new voltage reference occupies a silicon area of only 3,500 µm2, shows a power consumption of <30 µW and its DC power supply rejection is better than 65 dB.
