Charge Pump output Capacitance

Mushir

Hi 

 I am using a capacitive load in charge pump in CADENCE h035 technology. But when I am creating charge pump symbol and using it in other circuit   its showing errors while simulating (runs upto 1% and the spectre error) I know its due to the load at the output port of Charge pump but I dont know how to use it or replace it because that output capacitance is very important.

 Please suggest me something.

 Thanks in advance.

    Yeah I did a mistake while writing the technology and tools. I am using AMSh0.35um technology and Virtuosos 6.1.5 tool.  The actual problem is that when I am using the Symbol of this charge pump circuit with the output capacitor load and then integrating it with other circuit(basically a switch in this case) there is Spectre error coming. If I am using it without the load capacitance then its working fine. But I need the load capacitance in the charge pump.

    I have attached the circuit below.

    Thanks
