  • Abstract
    A continuous-time (RC)n lowpass filter is presented that can be fully integrated with cutoff frequency down to the 0.1 MHz range. The circuit is based on a cascade of new compact RC-cells that provides current amplification and filtering with minimum power dissipation (<15 μW/pole) using a single supply voltage (2 V). The high value resistance of the RC-cell is obtained by means of a current conveyor feedback that de-magnifies the signal current flowing in a small physical resistor. The circuit is intrinsically low-noise due to a `cooling effect´ in the equivalent resistor
