A design methodology of the analog currentmode bandwidth programmable integrator for a low voltage (3V) and low power application is developed and the integrator designed by this method is successfully fabricated by a 0.8µm CMOS n-well single poly/double metal process. The integrator ocuppies the active chip area of 0.3mm2. The experimental result illustrates a low power dissipation (1.0mW-3.55mW), 65dB of the dynamic range, and bandwidth programmability (10MHz-30MHz) with an external digital 4bit.
