Abstract
A coarse tuning synthesizer for wireless communication includes a digital control unit, a digital-to-analog converter, and a comparator. The digital control unit includes an output node coupled to a first input node of a VCO (voltage controlled oscillator). The digital-to-analog converter includes a first node coupled to the first input node of the VCO. The comparator includes an output node coupled to an input node of the digital control unit. The comparator also includes a first input node coupled to a second node of the digital-to-analog converter and a second input node coupled to an output node of the VCO.
