  • Abstract
    A 455 KHz IF filter suitable for AMPS cellular telephone applications has been developed in a 1.2 μm CMOS technology. The design is based on interspersion of repeated AGC and leapfrog gm -C stages. Including RSSI circuitry, the active area is 17 mm2. It draws 6.5 mA from a single ended 5 V supply. Measured results confirm a dynamic range of 64 dB and an S/(N+D) of 40 dB, sufficient for AMPS cellular applications
