Cochlea-inspired wavelet filterbank in sky130

License UPRJ_CI Caravel Build


This project implements a wavelet filterbank using switched capacitor techniques, as an extension of Tim Edwards's dissertation work (1999). The filterbank will be embedded inside efabless's Caravel frame in the nearest tapeout, and is derived from the cochlea_sky130 repo, so that this design can be embedded into Caravel (and not Caravan).

This work began as a class project for UCSD's BENG 207 Integrated Neuromorphic Bioelectronics (fall 2021).

All design and simulation was done using the sky1 virtual machine made by Karthi Srinivasan, shared during Telluride 2021.
