352 Harrison, Reid R.Micropower circuits for bidirectional wireless telemetry in neural recording applicationsState-of-the art neural recording systems require electronics allowing for transcutaneous, bidirectional data transfer. As these circuits will be implanted near the brain, they must be small and low power.
