Hi, all,
In some processes, I see some mim-caps are shielded with lower metal layer beneath the capacitor plates, and the design manual will suggest to connect the shielding to ground. I am wondering that whether the shielding is necessary for RFIC purpose? and what's the difference between connecting to GND and VDD? which one is better?
Best wishes, abcyin
