  • Sub-ranging digital to analog converter for radiofrequency amplification
    Patent number: 7183958
    Abstract: An apparatus and method for amplifying a radiofrequency signal using a main Digital to Analog Converter (RFDAC) and a subordinate Digital to Analog Converter (Sub-DAC). The main RFDAC provides a first portion of a N-bit digital output, which specifies the amplification level of the radiofrequency signal, and the sub-DAC provides a second portion of the N-bit digital word. Together, the main RFDAC and the Sub-DAC convert a complete N-bit digital word, where N specifies the resolution of the output radiofrequency signal.
