摘要：
A bioamplifier that includes a high pass filter, open-loop amplifier, and low pass filter in an area efficient design that can be used in implantable neural interfaces. The high pass filter can be implemented by using a switch-capacitance resistor coupled with parasitic capacitance of the electrode. The amplifier can be chopper stabilized and can include a high gain, current-ratio first stage followed by one or more dimension-ratio stages. The low pass filter utilizes the output impedance of the open-loop amplifier to form an embedded gm-C low pass filter.
