Abstract:
A bandpass filter comprising:a first capacitor connected to an input terminal of the bandpass filter;an output terminal;a first transconductor having a first input connected to a voltage reference;a second transconductor having a first input connected to an output of said first transconductor and to said first capacitor, and a second input;a second capacitor connected between the first voltage reference and an output of second transconductor;a monitor amplifier having an input connected to said second capacitor and to the output of said second transconductor, and an output connected to the output terminal of the bandpass filter;a third capacitor connected between the second input of said first transconductor and the output of said first transconductor; anda splitter bridge comprising a plurality of resistors connected in series between the output terminal of the bandpass filter and the voltage reference at a node, and the node connected to the second input of said second transconductor.
