Abstract

A circuitry (10) for recording a biological electrical signal comprises: a signal recording input (100) for receiving the biological electrical signal; a signal recording amplifier (110) for providing an amplified biological electrical signal at an output node (111); a sampling circuit (120) having an input node (121) connected to the output node (111) and configured to sample the amplified biological electrical signal; a feedback integrator (130) connected to the input node (121) and configured to provide a feedback signal into the signal recording amplifier (110), and to subtract a DC offset from the amplified biological electrical signal; a switch (140) for selectively disconnecting the output (111) from the input node (121); and a stimulation artefact detection block (150) for detecting a stimulation artefact; wherein the switch (140) is configured to receive a control signal dependent on detection of a stimulation artefact affecting recording of the biological electrical signal.
