REDUCTION OF SMALL SPURS IN TRANSMITTERS |
摘要 |
An apparatus for reducing spurs is described. The apparatus includes a coarse digital to analog converter (DAC). The apparatus also includes a correction term generator. The correction term generator generates a correction term. The correction term has an amplitude within a dynamic range of the coarse digital to analog converter (DAC). The apparatus also includes a baseband filter. The correction term is selected such that the baseband filter reduces the correction term to an amplitude approximating that of a spur in a transmit signal. The correction term is used to reduce a spur.
