hello every body
i am trying to design a simple inverter using 0.18um CMOS. output of inverter has jumps in the corners, how can i solve this problem?

Is it really a problem? Why? If you just don't like it, spend it a capacitive output load.

so many thanks for your reply, infact i am designing "bootstrapped switch in 0.18um CMOS" and i can not change circuit diagram, would you help me to transistor sizing for this circuit? i have attached the circuit as a picture(M4 and M5 are inverter) in the following link

would you help me to transistor sizing for this circuit?
Transistor sizing depends on
  • output impedance of the source @ Vin
  • input impedance of the load @ Vout
  • the clock frequency
I'd suggest to study the appropriate literature!

The problem you describe above seems to be a typical case for a circuit optimization software. My company (MunEDA) works in this field, you could check our website for case studies.
