A HIGH-VOLTAGE NEURAL STIMULATOR COMBINED WITH A LOW-VOLTAGE RECORDERHIGH-VOLTAGE NEURAL STIMULATOR COMBINED WITH ALOW-VOLTAGE RECORDERUlrich Bihr, Jens Anders, Joachim Becker and Maurits Ortmanns Institute of Microelectronics, University of Ulm, Ulm, Germany Ulrich.Bihr@uni-ulm.deAbstract: This paper presents a high-voltage (HV) neuralstimulator combined with a low-voltage (LV) neuralrecorder. In many bidirectional neural implementationswith a high voltage compliance for the stimulation is itnot possible to have a high density due to the high powerconsumption in the recording part with the same HV supply.This realization shows a stimulator with a HV supplyof 7.5V to enable high voltage compliance together witha neural recorder, which uses a LV supply of 1.65V tominimize the power consumption of the recording. In addition, the recorder split the neural signal into the localfield-potentials and the action potentials. With a separationand an individual amplification of the two sub signals to the maximum swing, it is possible to reduce the dynamic rangeand thus resolution of the required ADC. This results in amajor data reduction and reduces the power consumptionof the recording part. The implementation presents a stimulator with a maximum stimulation current of 15mA with5-bit resolution and 7-bit dynamic range combined with arecorder, which consumes 52W, and provides an input referred noise of 3.8Vrms for the LFPs and the APs.Keywords: Neural stimulator
