This paper presents a method to model external capacitors behavior face to continuous and transient events. Temperature and the physical dimensions of the capacitors have been considered in order to predict Electromagnetic Compatibility performances of an equipment or a system. The different tests were performed on ceramic capacitor series X7R from Murata. A model has been developed in Verilog-A....
Direct Electrostatic Discharge (ESD to connectors pins is used to evaluate the system level susceptibility. Nevertheless, it is difficult to determine accurately the sensitive areas. Indeed, the propagation of an ESD through a PCB is still very difficult to predict even for a simple system. The lack of models at both IC and PCB levels and the limited computational resources force to simulate the system...
Driver circuits using high side switches, are commonly used in electronic applications. A challenging aspect of the integrated circuit design of such driver circuits comes from the control of the state of the circuit with high reliability when it is under harsh electrical conditions. It includes safe operations and predictable behavior under high level of Electromagnetic Interference (EMI). The typical...
This paper reflects a part of electromagnetic susceptibility studies conducted on active circuits. An electromagnetic interference (EMI) is injected on a 5 GHz monolithic voltage-controlled oscillator (VCO). This circuit is implemented on a 0.35 μm BiCMOS SiGe process. Injection locking and pulling are put in evidence when the circuit is subject to a high frequency interference with possible frequency...
