Design of minimally invasive all-pole analog lowpass filters Academic Article uri icon


  • 2016, Springer Science+Business Media New York. In this paper, a new design technique for designing higher order minimally invasive lowpass filters is proposed. The proposed fully differential filter has been simulated in TSMC 130nm technology for third and fourth orders. When compared with the conventional filter implementations such as a Tow-Thomas architecture, the proposed third order solution achieves a total in-band input-referred integrated noise of 44.09V compared to 78.83V, achieved by a Tow-Thomas implementation. The proposed solution offers higher tolerance to blockers along with lesser number of active devices required. Though, the total capacitance used is increased from 23.82pF to 89.82pF, from third order Tow-Thomas filter to its minimally invasive filter counterpart, the power consumption reduces by 77% from third order Tow-Thomas to the third order minimally invasive filter.
