  • Patent number: 11235147
    Abstract: A charge balancing circuit is adapted to be connected to an electrode and to a stimulation source. The charge balancing circuit has an electrode terminal for receiving an electrode voltage, an amplifier coupled to the electrode terminal and adapted to amplify and invert the electrode voltage for generating an intermediate voltage and a compensation stage. The compensation stage is adapted to generate an output current if the electrode voltage lies outside a specified safety range and to generate the output current depending on the intermediate voltage. The compensation stage is further adapted to supply the output current to the electrode terminal for driving the electrode voltage towards and/or into the safety range.

  • Patent number: 11123000
    Abstract: A biocompatible recording system includes a number of input channels for acquiring electronic information from the neural system of a living being. The recording system includes a preamplifier and further amplifier stages. An input of a second amplifier stage is coupled to an output of the preamplifier. A low-pass filter having a capacitance multiplier is connected to the second amplifier stage. The preamplifier of the recording system is designed using P-MOS technology.

  • Patent number: 8129861
    Abstract: A voltage supply has a plurality of voltage sources to supply output connections. To achieve closed-loop control of the output voltage at the output connections, a closed-loop control circuit is provided that has an actuating element for each voltage source, and each respective actuating element has a current path via which a connection of the respective voltage source can be connected to an output connection. Each actuating element has an actuating signal input for setting the electrical conductivity of its current path. The closed-loop control circuit has a closed-loop controller to which the output voltage and a desired voltage signal are supplied. When a deviation occurs between the output voltage and the desired voltage signal, the closed-loop controller interacts with at least one actuating signal input in order to reduce the deviation.
