Dear All:
I need to integrate an on-chip capacitor (~40pF) in the loop filter and it is a MOM cap consisting of M1-M8. To fully utilize the area, I want to place the power lines on top of the capacitor by using thick copper and Aluminium M9-M11. The power line serve as VDD and GND only for analog circuits. Has someone done this before and what could be the potential problems? Or it is acceptable?
Thanks in advance!
