A novel cascadable current-mode universal filter employing three current-controlled conveyors (translinear conveyors) and two grounded capacitors is proposed. The circuit with single input and three high-impedance current outputs, ideal for cascading, realizes low-pass, band-pass, and inverting band-reject transfer functions. Inverting high-pass and inverting all-pass transfer functions are obtained by simply connecting the available outputs. The proposed circuit enjoys tuning through external currents, low total harmonic distortion (THD), good dynamic range, attractive sensitivity performance and is ideal for IC implementation.
