Abstract: In this paper, the susceptibility of a Kuijk bandgap voltage reference to electromagnetic interferences (EMIs) superimposed to the power supply is investigated. A model of the bandgap circuit is derived from experimental tests consisting of scattering parameters and susceptibility measurements on a test chip. The model is able to correctly predict the susceptibility of the circuit by means of SPICE transient simulations. The simulations identify the fundamental stray components responsible for EMI coupling tha…
