Techniques for static and dynamic input multiplexing for high-density neural signal recording are disclosed herein. A multiplexer can receive a first set of neural signals via inputs. A subset of the first set of neural signals above a threshold can be determined. A group of the inputs corresponding to the subset of the first set of neural signals can be determined. Operation of the multiplexer can be modified to block inputs not in the identified group of the inputs. A second set of neural signals can be received into the multiplexer via the group of the inputs. The second set of neural signals can be transmitted to a plurality of channels of an amplifier while blocking inputs not in the identified group of the inputs. The second set of neural signals can be amplified using the amplifier. The amplified second set of neural signals can be transmitted for further processing.

Static and dynamic input multiplexing for high-density neural signal recording

A three-level encoding transmitter is disclosed in which a transmitter circuit is configured to receive an input data signal including binary data and transmit an encoded data signal. The transmitter circuit can include an inverter circuit configured transmit first and second voltages for each logical level of the binary data. A transmission control circuit can cause the inverter circuit to transmit the voltages or deactivate the inverter circuit based on a first control signal. The transmitter circuit can further include an idle circuit configured to transmit an idle voltage between the first and second voltages when there is no data transmission. The idle circuit may transmit the idle voltage based on a second control signal. The first and second control signals may be configured to only be active when the other is inactive.
