Abstract :
This paper is concerned with design and an integrated circuit implementation of a multicarrier quadrature phase generator for application in analog spectral synthesis and orthogonal frequency division multiplexing transceiver using amplitude phase shift keying using 0.18μ technology. A noble analog or sampled data based rotational quadrature oscillator has been designed for generating quadrature signals. Scheme of multicarrier generation studied includes multiple frequency generation, using regenerative frequency dividers and mixers. Simulation results and performance of multicarrier generation have been presented. This scheme shows very low power consumption than typical method of multi-frequency signal synthesis using IFFT.
