Abstract :
This paper presents the design of a 5th low-pass continuous-time Bessel filter, which is realized using a CMOS transistors-only approach and a pseudo-differential topology. It achieves a 57 dB minimum dynamic range even under 0.9 V supply voltage. The power consumption is as low as 10.5 μW at the nominal 100 kHz cutoff frequency, while the total chip area is only 0.2 mm2
