Abstract

Two novel OTA based capacitor multiplier circuits are proposed. First capacitance multiplier circuit is based on OTA based impedance multiplier reported earlier. Other capacitance multiplier is an improved version of the current-mode capacitance multiplier reported earlier, where in the DO-OTA is used instead of current mirror which senses the input current and scales it by a factor (k+1) such that a scaled version of input current flows through the capacitor (Ic = Iin/(k+1)). The first capacitance multiplier uses grounded capacitor and the second one uses a floating capacitor. The capacitor multiplier circuits are verified using TINA SPICE simulator
