Patent ID: 7358885

Claim:
A receiver, comprising: a mixing digital-to-analog converter (DAC), comprising: a radio frequency (RF) transconductance section having an input for receiving an RF signal and an output for providing an RF current signal; and a switching section coupled to the RF transconductance section, the switching section having inputs for receiving bits associated with a digital local oscillator (LO) signal and having an output configured to provide an analog output signal, and wherein a DAC of the mixing DAC is implemented as a segmented DAC having a thermometer encoded DAC section and a binary encoded DAC section; a direct digital frequency synthesizer (DDFS) having outputs configured to provide the bits associated with the digital LO signal to the inputs of the switching section; and a dynamic element matching (DEM) circuit coupled between the outputs of the DDFS and the inputs of the switching section that are associated with the thermometer encoded DAC section, wherein the DEM circuit is configured to scramble the bits provided to the thermometer encoded DAC section.
