Abstract :
A new polyphase filter for implementing the channel select filter for Bluetooth low-IF receiver is presented. It is based on the simplest type of active elements namely current and voltage followers. The center frequency is digitally tuned through programming active current division networks. Experimental results obtained from a 6th-order fully differential filter fabricated in a 0.35 mum CMOS chip are provided.
