  • Abstract
    A bilinear switched-capacitor filter realisation of leapfrog type is proposed, which is compensated for the DC offset voltage of the amplifiers. By using offset-compensated integrators in combination with unity-gain buffers, a filter can be realised which operates with a two-phase clock. The realisation is parasitic-insensitive.
