Method and system for digital to analog conversion for power amplifier driver amplitude modulation

Abstract

Aspects of a method and system for digital to analog conversion for power amplifier driver amplitude modulation are presented. Various aspects of the system may include circuitry that enables oversampling, within a single integrated circuit device, of each of a plurality of samples in a digital baseband signal. The circuitry may enable reduction of a number of bits, i.e., coarse quantization, in each of the oversampled plurality of samples so as to cause displacement of the quantization noise that occurred as a result of the coarse quantization. A subsequent signal may be generated based on the oversampled signal. The circuitry may enable the subsequent signal to be low-pass filtered utilizing filter circuitry in the single integrated circuit device, thereby attenuating the quantization noise displaced into the higher frequency range of the oversampled signal.
