Abstract

Adigitally controlledmultiphasesinusoidal oscillator (DCMSO) circuit employingdigitally controlled current conveyors (DCCCII) and grounded capacitors is presented. In the proposed circuit, voltage-mode inverting first-order low-pass sections are utilized to arrive at a circuit capable of producing multiphase sinusoidal waveforms. The oscillation conditions and oscillation frequencies are orthogonally (or independently) controllable. The use of grounded capacitors ensures viability for monolithic integrated circuit implementation. Results of PSPICE simulations confirm the proposed theory.
多相正弦振荡器与数字控制
提出了一种采用数字控制电流传送带(DCCCII)和接地电容的数字控制多相正弦振荡器(DCMSO)电路。在所提出的电路中,利用电压模式反相一阶低通部分来得到能够产生多相正弦波的电路。振荡条件和振荡频率是正交(或独立)可控的。接地电容器的使用确保了单片集成电路实现的可行性。PSPICE模拟结果证实了所提出的理论。
