A new, single CCII- based, voltage-mode, first-order, all-past filter and its quadrature oscillator application

In this paper, a new voltage-mode (vm) rst-order all-pass filter (apf)topology composed of only a grounded capacitor is proposed. the proposed apf uses asingle, minus-type, second-generation, current conveyor (ccii-), which can be constructedby only ve mos transistors. it has low power consumption. the resonance frequency ofthe proposed apf can be adjusted by changing only a resistor value. however, it needsa 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 domainand frequency domain simulation results and an experimental test result are included toconrm the theory.
