Multiphase sinusoidal oscillator circuits are presented NEFF N50 HLAWD53N0B Built-In Solo Microwave 900 Watt 25 L - Black which utilize Operational Transresistance Amplifier (OTRA) as the active element.The first circuit produces n odd-phase oscillations of equal amplitudes and equally spaced in phase.The second circuit is capable of producing n odd- or even- phase oscillations equally spaced in phase.

An alternative approach is discussed in the third circuit, which utilizes a single-phase tunable oscillator circuit which is used to inject signals into a phase shifter circuits.An automatic gain Tick Defense control (AGC) circuit has been implemented for the second and third circuit.The circuits are simple to realize and have a low component count.

PSPICE simulations have been given to verify the theoretical analysis.The experimental outcome corroborates the theoretical propositions and simulated results.
