Abstract

In this paper, a new Voltage-Mode (VM) first-order All-Pass Filter (APF) topology composed of only a grounded capacitor is proposed. The proposed APF uses a single, minus-type, second-generation, current conveyor (CCII-), which can be constructed by only five MOS transistors. It has low power consumption. The resonance frequency of the proposed APF can be adjusted by changing only a resistor value. However, it needs a single matching condition. As an application, a quadrature oscillator example is given. A non-ideality analysis for the proposed APF is also given. A number of time domain and frequency domain simulation results and an experimental test result are included to confirm the theory. (C) 2015 Sharif University of Technology. All rights reserved.
