The chip is composed of eight 16-channel front-end blocks, data serializing circuits, a DSP for on-chip spike sorting, digital MUX, encoder, UWB TX, and bias generators. The chip operates in one of the two modes. In sorting mode, a selected channel is connected to the on-the-fly spike sorting block and the extracted features of the spikes are transmitted for off-chip classification. In streaming mode, all the sampled data from the 128 channels are recorded and transmitted without any additional processing.
