Patent ID: 7415260

Claim:
A current-mode direct conversion receiver comprising: an input voltage-to-current converter stage; a downconversion mixer coupled to the input voltage-to-current stage; a current-to-voltage filter stage coupled to the downconversion mixer; and an active correction stage coupled between the input voltage-to-current converter stage and the downconversion mixer; wherein the input voltage-to-current converter stage is operable to receive a voltage-mode modulated RF signal and from the voltage-mode modulated RF signal generate a current-mode modulated RF signal; wherein the active correction stage is operable to isolate the current-mode modulated RF signal from voltage changes due to the downconversion mixer; wherein the downconversion mixer is operable to generate current-mode quadrature baseband signals through mixing the current-mode modulated RF signal to baseband at an operating frequency; and wherein the current-to-voltage filter stage is operable to generate from the current-mode quadrature baseband signals voltage-mode modulated signals corresponding to the voltage-mode modulated RF signal.
