Abstract

See full text

This disclosure provides a neuromodulation device for measuring a biological electrical signal in response to a neural modulation of biological tissue. The neuromodulation device comprises at least one amplifier circuit (20), which is used to amplify an input voltage signal that is based on the biological electrical signal. The amplifier circuit (20) suppresses a common mode (CM) voltage signal in the input voltage signal. The amplifier circuit (20) comprises an input stage (21) to receive the input voltage signal, and a differential transconductor (23) to provide an output current signal based on a DM voltage signal in the input voltage signal. The transconductor (23) provides a first CM voltage signal and a second CM voltage signal to a CM amplifier (27) of the amplifier circuit (20). The CM amplifier (27) combines the first CM voltage signal with the second CM voltage signal with an inverting gain, and provides the inverted CM voltage signal back to the transconductor (23) for enabling the CM suppression.
