Abstract :
A new design technique for minimally-invasive all-pole analog lowpass filters is introduced. The proposed method has minimal impact on the in-band signal in terms of added noise and nonlinearity, whereas it has comparable performance for out-of-band signals with smaller number of active devices. Simulation results for third and fifth order lowpass filters show good improvement in in-band linearity when compared to conventional filter topologies.
