Lab Overview:
This lab contains the schematic and layout of Our test chip layout to for submission to MOSIS. The Chip contains the following separate circuits circuits:
A 31-stage ring oscillator with a buffer for driving a 20 pF off-chip load.
NAND and NOR gates using 6u/0.6u NMOSs and PMOSs.
An inverter made with a 6u/0.6u NMOS and a 12/0.6 PMOS.
6u/0.6u 4-terminal PMOS transistor.
6u/0.6u 4-terminal NMOS transistor.
A 25k-10k resistor voltage divider.
An 8 bit serial to parallel converter.
