Operating Point Analysis<br />

See “.OP RF” in the Eldo RF User’s Manual for more information.<br />

Operating Point Analysis Results<br />

The DC operating point is saved to the .chi file. Information concerning the operating points<br />

such as power dissipation, node voltages, and source currents are output to the .chi file.<br />

Example results:<br />
