Abstract:
An area efficient baseband filter is disclosed. In an exemplary embodiment, an apparatus includes a current to voltage (I-V) filter configured to receive an input current signal at an input port and generate a filtered output voltage signal at an output port based on a feedback transconductance. The input current signal comprises an input DC current in addition to a signal current. The apparatus also includes a feedback circuit connected between the output port and the input port, the feedback circuit having at least one transistor configured to couple the input DC current to a signal ground and to provide the feedback transconductance for the I-V filter.
