Dynamic DC Current Source: DC_I

Symbol

Summary

DC_I combines the functionality of the DCCS and DCCSS into one current source.

Parameters

Name Description Unit Type Default
ID Current source ID Text I1
Sweep Current sweep type    

Parameter Details

Sweep. Specifies whether DC current is swept. Choices are None, Vector, Linear, Linear (# pts), Log (Dec) and Log (Oct).

Dynamic Parameters

Name Description Unit Type Default
I DC current Current 1000 mA
IStart DC current start Current 0 mA
IStop DC current stop Current 5000 mA
IStep DC current step Current 1000 mA
NumPts Number of swept current points   2

Dynamic parameters are parameters whose existence depends on the settings of the static parameters. The following is a list of all parameters that can appear for the DC_I depending on the setting of the static Sweep parameter.

Dynamic Parameter Details

I. Appears when Sweep is None or Vector. If Sweep is None, I represents a single DC current value. If Sweep is Vector, V represents a vector of swept current values.

IStart, IStop.Appears when Signal is Sinusoid and Sweep is Linear, Linear (# pts), Log (Dec) or Log (Oct). Allows you to specify the start and stop current values in a current sweep.

IStep. Appears when Sweep is Linear. Allows you to specify the current step value of a current sweep.

NumPts. Appears when Sweep is Linear (# pts), Log (Dec) or Log (Oct). Allows you to specify the number of points in a current sweep. For Sweep is Log (Dec) or Log (Oct), this represents the number of points per decade and octave, respectively.

NOTE: Cadence® AWR® simulators add some series resistance to this element during simulation. This may affect results if injecting current into a large resistance. To change the value of the resistance, choose Options > Default Circuit Options to display the Circuit Options dialog box, then click the AWR Sim tab and under Convergence Aids specify the Series source resistance.

Layout

This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
