This paper proposes a method to design a flat pass-band gain with two RC band-stop filters for a 4-stage passive RC polyphase filter in a Bluetooth receiver. Based on the superposition principle, the transfer function of the poplyphase filter is deri

RC polyphase filter is a complex analog filter and has asymmetric frequency characteristics with respect to DC. It is composed of resistors and capacitors, and has complex analog input / output ports. Since this type of filter can partially realize H
