Abstract :
A CMOS IF band-pass filter for an integrated Bluetooth receiver is presented. The filter center frequency is 3MHz and has bandwidth of 1MHz. The filter is based on unity gain cells and utilizes linearized MOS resistors for tuning. The proposed filter occupying an area of 1.7mm×1.7mm was submitted for fabrication using a regular 1.2-um CMOS process. Simulation results obtained from the layout circuit file show that the proposed filter satisfies the selectivity and dynamic range requirements of Bluetooth.
