Modular log-domain filters
Jirayuth Mahattanakul, C. Toumazou · Electronics Letters · 1997
A new modular approach for realising log-domain filters is proposed. By using this approach, nonlinear Gm-C filter structures can be readily transformed into log-domain filters with linear transfer characteristics. The realisation of the log-domain integrator and biquad filters is demonstrated and the simulation results presented.
