Abstract :
A second-order current-mode bandpass filter employing current controlled conveyors and implemented in BICMOS technology is presented. Both high center frequency f0 and high Q value have been achieved with low power consumption. A 85MHz IF stage for a mobile communication terminal, based on the cascade of two former cells, has been realized. Measurements results are obtained in good accordance with simulation ones. The active area of the 4th order filter is 0.8mm2 and its static power consumption is 25mW under ±2.5V supplies.
