Abstract :
In this paper a continuous-time 4th order Butterworth lowpass filter based on current-mode processing is presented for applications over the video frequency range. Using a very low-cost 2.4 μm CMOS process (Mietec), the circuit occupies 2.8 mm2 and consumes 19 mW from a ±1.5 V supply. Experimental results are given for a 4.5 MHz to 12 MHz tunable lowpass filter with 58 dB of dynamic range at 10 MHz
