A new circuit configuration for continuous time universal filters using current and voltage followers is proposed. The new configuration employs small number of passive elements. It provides independent control over all filter design aspects mainly the natural frequency, ωo, quality factor, Q, and gain. It also allows complete MOS non-linearity cancellation, thus is suitable MOS-C continuous-time fully integrated filters. Analysis of the non-idealities associated with the active elements is included. HSpice simulations that confirm theoretical analysis are included.
