En 2016 IEEE Biomedical Circuits and Systems Conference (BioCAS) (368-371), Shanghai, China: Institute of Electrical and Electronics Engineers.978-1-5090-2959-4https://hdl.handle.net/11441/89728This paper presents design principles for reusing charge-redistribution SAR ADCs as digital multipliers. This is illustrated with an 8-b fully-differential rail-to-rail SAR ADC/multiplier, designed in a 180 nm HV CMOS technology. This reconfigurability property can be exploited for the extraction of product-related features in neural signals, such as energy content, or for the discrimination of spikes using the Teager operator.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess10.1109/BioCAS.2016.783380821259359
