→Summary of Spring 2009 Work: added related files
The final few weeks of the semester were spent laying out components in the PCB view of Altium. As of right now, a compact design for an amplifier measuring 0.183”x~1.3” has been completed. Making use of 0201 size components, this amplifier is approximately .2” shorter than the old design, despite incorporating an extra transistor. The amplifier design features an isolating ground trace running the length of the amplifier to prevent crosstalk between channels. A prototype layout of the summing circuit has also been completed, though some layout issues there remain to be resolved over the summer.
