COND
This function does the following:
• If 1st expression < 2nd expression, returns 3rd expression.
• If 1st expression ³ 2nd expression, returns 4th expression.
Syntax COND(1st expression,2nd expression,3rd expression,4th expression)
If value of 1st expression or a 2nd expression is invalid, the value for the previous
measurement index number is used for the comparison.
Example COND(ID-VG,SQRT(ID)-VG,VD,VGS-VTH)
returns:
• VD if ID-VG < SQRT(ID)-VG.
• VGS-VTH if ID-VG ³ SQRT(ID)-VG.
