In this project, we will explore and develop a novel charge balancing technique for neural stimulation based on analog/mixed-signal circuits.
Electrical stimulation is widely used in standard clinical practice. To achieve good spatial selectivity, temporal interference stimulation is introduced recently. This new approach includes two pairs of electrodes delivering sinusoid current. The stimulation frequencies of the two sinusoids differ by a low delta frequency. By modulating the amplitude of the sinusoid current, the distribution of the electric field can be steered to different positions.
challenge for this stimulation approach is to balance the delivered charge for
each electrode output. The unbalanced charge will introduce an offset voltage
build-up onto the electrode over time, which can cause safety issue and impair stimulation
In this project, we will explore and develop a novel charge balancing technique to address this issue based on analog/mixed-signal circuits. We will design and implement an offset detector, a logic control loop, a change balancing loop, etc. If the development fits the project need, there is an option to tapeout the circuit.
The tasks in this project include:
