A 0.47mW 6th-order 20MHz active filter using highly power-efficient Opamp

This paper presents an ultra-low power 6 th -order 7MHz-to-20MHz tunable active-RC low-pass filter. Due to the proposed highly power-efficient Opamp, the filter only consumes 0.47 mA power from 1.8 V supply voltage, corresponding to 3.86 pW/Hz/pole normalized power. The Opamp utilizes an adaptive-bi...
