Hello, I am designing an IC amplifier and i want to remove the DC component from the output. I thought of using a capacitor. How can i implement a capacitor using a MOSFET. I heard i can connect the drain to source but how do i control the equivalent capacitance?
MOSFET capacitance is simply the gate capacitance.
HOWEVER: There is a series resistance component which varies with bias, and it is NOT modeled by the MOSFET Spice model alone.

I think you need to spend some more time learning the process. You may have a capcitor option wich gives less voltage dependence by using a high implant, or possibly poly-poly capacitor.
