Hi guys,
I have a circuit with maximum current of 20mA. I am using a p+ poly resistor to the circuit with estimated layout size 1.5umx12um with sheet resistance 400ohm/sq.
From one of the book it is written that
p+ poly resistor 150ohm/mm2, max current 0.65mA/mm2.
How can I relate the maximum current applied to the circuit, current density and layout size of this p+ poly resistor? Will the layout of the p+ poly resistor able to sustained the max current of 20mA?
Thanks
