Example 16—Transient Analysis of an<br />

Integrator<br />

Netlist file: tran_integrator.cir<br />

This example deals with the transient analysis of a second order delta sigma modulator circuit.<br />

A simple integrator, using analog macromodels (ideal switches, comparator, nand gates, and so<br />

on). Eldo provides a rich library of analog, digital, and switched capacitor macromodels, which<br />

can be useful for system simulations. All these macromodels are described in the Eldo<br />

Reference Manual. Transient analysis is performed to obtain the time domain response.<br />

Summary of Eldo commands used in this example:<br />

• .MODEL—Model definition.<br />

• .TRAN—Transient analysis.<br />
