Error control in circuit transient analysis

Error control in circuit transient analysis

The frequency warping error occurring in transient circuit analysis and the manner to control it are revisited. A new algorithm for the time step choice, based on an energy balance error, is proposed. An example shows that this new algorithm rejects fewer time steps than the SPICE one.
