Abstract:The realization of the current-mode quadrature sinusoidal oscillator was presented in this paper. In this design, a single active building block, named Current Differencing Cascaded Transconductance Amplifier (CDCTA) was used with grounded resistor and two grounded capacitors. The proposed circuit was a simple structure which was attractive for integrated circuit implementation. The proposed oscillator could generate two sinusoidal signals with 90°degree phase difference. The output current nodes were high imp… Show more
