✦ Synopsis

A concise macromodel of sample-and-hold circuits for the simulator SPICE is proposed. This generalized model is independent from actual technical realizations and is based upon compromises regarding the representation of exact circuit structures in the model. Different types of feedback and hold capacitor connections corresponding to the standard external circuit application are accounted for in the model internally. The macromodel allows one to simulate arbitrary user circuits with respect to the behaviour in both the time and frequency domains including error parameters and the temperature dependence of several parameters. Model parameters are extracted for the integrated sample-and-hold circuit AD585 from Analog Devices as an example. Simulation results and selected diagrams are compared with the manufacturer's data. 1997 by John Wiley & Sons, Ltd.
