Abstract

The current-mode first-order multifunction filter based on log-domain integrator is proposed in this paper. The filter consists of sixteen bipolar junction transistor (BJT) and one capacitor. The main circuit operation is divided into 2 parts: a log-domain lossy integrator and a current mirror circuit. The proposed filter has one input and three outputs: low-pass, high-pass, and all-pass responses. All the output signals are produced from the summing and subtracting of the currents in each branch of the output stage. The PSpice simulation results were used to verify the principle and theory.
