| Summary: | 碩士 === 中原大學 === 電子工程研究所 === 94 === A voltage-mode first-order allpass filter using one differential difference current conveyor (DDCC), one grounded capacitor and one floating resistor is presented. No passive component matching constraints are required. Because the output impedance of the proposed allpass filter is low, the output terminal can be directly connected to the next stage.
Using the proposed first-order allpass filter as basic building block, new quadrature oscillator and even-phase sinusoidal oscillators can be obtained. The simulation results confirm with the theoretical analysis.
