Abstract: A headstage for a Neural Data Acquisition System is shown and described. In one embodiment, the headstage includes at least one Input Pre-amplifier, and a multiplexer (MUX) for multiplexing at least one channel. In one embodiment, the input filter of the Input Pre-amplifier is tuned by adjusting the gate voltage of a transistor operating in sub-threshold mode.
