Abstract: An electrode arrangement for stimulating and recording electrical signals in biological matter comprises: an array (110) of electrodes (112), wherein electrodes (112) are configured to be switchable between stimulating and recording of electrical signals; a control unit (120), wherein the control unit (120) is configured to select a plurality of electrodes (112) to form a combined macroelectrode site (114) for providing a stimulating signal, wherein the control unit (120) is further configured to determine a perimeter electrode (112b) and a central electrode (112a), wherein the perimeter electrode (112b) is arranged at a perimeter of the combined macroelectrode site (114) and the central electrode (112a) is arranged centrally within the combined macroelectrode site (114), and wherein the control unit (120) is further configured to provide a stimulation signal to the perimeter electrode (112b) that has a lower magnitude than a stimulation signal provided to the central electrode (112a).

Abstract: An analog-to-digital converter, ADC, module is configured to operate in a coarse conversion ADC phase, and a fine conversion ADC phase comprising a delta modulation loop for tracking a signal, wherein the ADC module is configured to, at initiation of input of an analog signal, operate in the coarse conversion ADC phase for determining a coarse digital value; wherein the ADC module is configured to, when the coarse digital value is determined, operate in the fine conversion ADC phase, receive the coarse digital value as an initial approximation of the analog signal and track the analog signal during a finite duration.
