A digitally controlled multiphase sinusoidal oscillator (DCMSO) circuit employing digitally 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...
Some multiphase sinusoidal oscillator circuits either employing two output second generation current conveyors [DOCCIIs] or multioutput current conveyors [MO-CCIIs] as the active devices with grounded passive components are proposed. Two [DO-CCII]-based oscillators can generate odd-phase and some even-phase output voltages while the other two can generate both odd-phase as well as even-phase output...
A new current-mode quadrature oscillator using two translinear current conveyors and two grounded capacitors is presented. The proposed circuit provides two high output impedance current sources with 900 phase difference. The oscillation frequency can be controlled electronically by adjustting the bias currents of translinear current conveyors. The proposed circuit employs only grounded capacitors...
