This paper discusses RF substrate coupling in automotive integrated circuits. Analyses have been accomplished by measurements on wafer level. For this purpose test structures have been designed using a technology with partial dielectric isolation for automotive applications. The determining parameters to RF substrate coupling have been evaluated by(More)
This paper investigates techniques to improve the performance of analog circuits and reduce their sensitivity to coupled electromagnetic interferences (EMIs). A bandgap has been chosen for these analyses. RF noise is injected into an aggressor line couples and causes circuit functional failure. The efficiency of design techniques as an increase of bias(More)
This paper discusses RF substrate coupling in smart power integrated circuits. Analyses have been accomplished by measurements on wafer level. For this purpose test structures have been designed using a BCD technology (Bipolar, CMOS (complementary MOS) and DMOS (double diffused MOS)) for automotive applications. The determining parameters to RF substrate(More)
This paper introduces a low dropout (LDO) voltage regulator with an integrated current monitor, which sets a new performance benchmark in terms of RF immunity. Compared to classic topologies the proposed circuit succeeds in a very high robustness against RF disturbances which are superimposed into the regulator's battery voltage (VS) pin and output (OUT)(More)
This paper deals with the susceptibility to radio frequency interference of smart power integrated circuits. A method to perform simulations aimed at evaluating the performance of subcircuits included in a more complex IC in the presence of EMI is presented. Referring to this, the behaviour of a current sensor included into a high-side power switch during(More)
This paper studies and compares the RF immunity of DC current regulators against electromagnetic interferences (EMIs). The effect of EMI on the performance of a classic topology is analyzed. It turns out, especially the regulators output is very sensitive against EMI since disturbance levels in the millivolt range cause serious malfunctions. Subsequently(More)
