I need to design an electric circuit which require PWM to let the battery and supercapacitor take turn to supply current to the loads.
stage1: battery charge up supercap and supply current to the load
stage2: supercap voltage increase to a certain level, battery current is cut, supercap supply current to the loads
stage3: voltage of supercap decrease to certain level, again, battery supply current to load and supercap.

my pwm and switch is not functioning well,
the positive input signal undergoes damping oscillation
and the switch (nmos) does not switch off as Vs>Vg
can anyone help me in this project? I will provide any information if require to..
