PCB Design for Rapid Charge/Discharge of Capacitor

Question

I need your advice: I am very new to electrical engineering, and I would like to design a PCB that allows me to rapidly charge/discharge capacitors. I would like to use a PIC to control MOSFETS that open/close voltage inputs from an external power supply to capacitors.

I thought about using this scheme for the switch:

... but I am not sure if this is a good approach since I would need a high OHM resistor to charge up my capacitor quickly (reduce drainage as much as possible) and to avoid excessive currents, but then on the downside, it would also slow down the discharge rate of the capacitor.

Hence, I was wondering, if someone knows a better approach of how to deal with such switching?

EDIT

Based on the comments and an answer, I tried to implement the two-MOSFET switch, as suggested:

Unfortunately, I must have done something wrong with my setup. Have a look at the transient analysis plot: The capacitor does not seem to be completely discharging.

EDIT 2

Another switching scheme that seems to work this time:

Here is the result:

Answer 1

That resistor will drain continuously your capacitor, so it will charge up and then slowly discharge. Also be wary of the gate requirement of your P-channel mosfet, unless you are charging to 5V you'll need to translate the level.

What do you need, as already commented, is two mosfet, a P-channel for charging and an N-channel for discharging. This is usually known as half-bridge and it's widely used for controlling, like, everything.

When using dedicaded ICs you can use an N-channel even for the high side (N-channels are cheaper and works better, but you need a floating Vgs to drive them).

They actually sell packages with one, two (brushed DC motor), three (brushless motor control) and maybe more half legs with all the drive circuitry and protection needed. Just supply a logic level. Major IC manufactures make them, I'd start with ON Semi, Infineon, Allegro and even TI (not an exhaustive list, of course)

Be careful with caps since the surge current can be quite big. Sometime for the discharging part only SCRs are used since they tend to perform better for the job.
