This paper presents a parametrized VLSI architecture for an n-state Kalman filter implementation intended for real-time applications that typically require a sensing rate not far from 300 samples per second. The architecture has been optimized in silicon area and power consumption. This approach has been proved with a fabricated chip using a 0.5 µm CMOS technology. The fabricated integrated circuit executes a two-state Kalman filter employing 70 K transistors. For a performance of 50 filter iterations/second, the chip requires a clock frequency of 200 KHz where a negligible power consumption of 1.1 mW is observed. This performance can be increased up to 176,991 iterations/second at a clock frequency of 20 MHz.
