Abstract:
A set of Matlab .m files used to find optimal values for the aLIGO RFPDs. The code (written by Rana) returns the top 5 solutions that yield maximum SNR as defined by a weighted cost function. The file descriptions are as follows:

snrfind2.m - This is the main optimizer code. Set operating frequency and number of iterations.

pdsnr2.m - Set operating frequencies, opamp noise, analysis temperature, and cost function weighting parameters.

pdz.m - Called to calculate the RFPD transimpedance and "back" impedance as "seen" looking out the RF opamp positive input.
