Symbolic model reduction in transient mode with Analog Insydes
This notebook shows the symbolic model reduction in transient mode. It presents new user-defined simulation and error functions and its usage in the model reduction routine.
Symbolic model reduction in small signal mode of a modern voltage limiter circuit
This notebook shows the symbolic model reduction in mixed DC/AC mode of a modern circuit consisting of BSIM3v3-transistors. The power supply rejection (PSR) capacity of a voltage limiter circuit was designed with a mosfet operational amplifier of elements. It has been calculated over an interval of frequencies from 100 Hz to 10 MHz. Both, the original system of equations and the reduced one, have been evaluated, and the two results have been plotted in the same graph for comparison. This circuit was developed by the Fraunhofer IMS.
