Maximum Allowed current in 0.18um UMC CMOS

[pavan5720]

Please let me know the valve , in the documentation its given 625u amp , is this value correct

But in some VCO designs the tail current source value is above 2mA, some papers even 7mA.
Please let me know answer at the earliest

My guess is you are looking at the saturation current. That is usually given in uA/um or it could be for a specific transistor width. If you use a wider transistor you can have more current.
