1. Final Chip Design

2. Introduction
In this lab a capacitor and op-amp were designed and inplimented on the previously created padframe to complete the chips design. The final chip design had to pass both DRC and NCC checks with no errors.

3. Materials and Methods
The final components needed to complete the chip were an op-amp and capacitor. These components were designed in ElectricVLSI. The op-amp was comprised of the bias circuit allowing the op-am to reach maximum gain. Along with the bias circuit the op-amp was comprised of a differntial pair with and a current mirror. Down stream of that was a gain stage comprised of transistors boosting the op-amp signal.  The last component in the op-amp was a 10pF capacitor used to stabalize the circuit.
The op-amp and the invertor, built in a previous lab, where then placed on the padframe layout. They were wired into the exported pins on the padframe on both the padframe layout and schematic. DRC and Ncc checks were than ran on the circuit. The circuit passed with no errors and was ready to be sent to the manufaturer to be built.

5. Discussion
The final IC chip design was DRC and NCC clean, with no errors. The chip is ready to be sent to the manufactureer to be built. The final design of the chip was not with out much trouble shooting correcting errors to make the circuit DRC and NCC clean. This project was a tremendous learninmg opportunity no only in how to design an IC chip but the theroy behind it and how the over all system works.
