A bandpass filter includes a first and a second transconductor. The first transconductor has a first input connected to ground, and a second input connected to a second input of the second transconductor and to the output of the filter. An output of the first transconductor is connected to a first input of the second transconductor, and to an input of a filter through a first capactor. The output of the second transconductor is connected to ground through a second capacitor, and to a monitor amplifier. An output of the monitor amplifier is connected to the output of the filter. The bandpass filter further includes a third capacitor arranged between the second input and the output of the first transconductor, and a splitter bridge connected to the second input of the second transconductor.
