This paper presents an extended model for transient and ac circuit-level simulation of minority carriers propagation through the substrate of smart power integrated circuits (ICs). A p-n junction and a diffusion resistor with capacitive components are proposed to efficiently simulate transient parasitic coupled currents in high-power stages. From a general chip layout, an equivalent substrate network...
This work concerns a dedicated mixed-signal power system dynamic simulator. The equations that describe the behavior of a power system can be decoupled in a large linear system that is handled by the analog part of the hardware, and a set of differential equations. The latter are solved using numerical integration algorithms implemented in dedicated pipelines on a field programmable gate array (FPGA)...
This paper addresses the simulation of switched-capacitor circuits including capacitor nonlinearities at an intermediate modelling level, filling the gap between device level and behavioural level simulators. Starting with the resolution of the trivial case of integrator with ideal components, the impact of first- and higher-order capacitor nonlinearities is analyzed in detail and the related simulation...
This paper focuses on a new pipelined processing unit architecture dedicated to mixed-signal power system emulation. Prior research in this field has proven that analog emulation overcomes the speed limits of numerical simulators with reliable accuracy. Then, a new concept based on field programmable power network system (FPPNS) has been developed in order to gain in term of flexibility. It is based...
