Help for LT spice simulation for a capacitve sensor circuit

Screen shot 2011-06-21 at AM 01.16.45.png
can any kind soul please help me on this?
I have a capacitive sensor whose initial capacitance is 34.5pF and will go up to 35.2pF.
I need to take in the capacitance and output a voltage value.

capacitive sensor -> capacitive measurement circuit -> output voltage valueIEEE Xplore - A low-power capacitance measurement circuit with high resolution and high degree of linearity

Which tool you want to use LT Spice or PSpice? Your Thread subject line reads PSpice, while in body you mentioned LT Spice. Anyway you can use PSpice to simulate above circuit. Ask in case you run into any specific issue.
