摘要： An integrated circuit radio transceiver comprises an integrated phase shift mixer for generating a phase and frequency shifted output signal to at least a portion of one of a transmitter or receiver front end. The integrated phase shift mixer includes a phase shift block that is operable to produce a phase shifted current signal at an output of the phase shift block and a mixer that is operable to produce the phase and frequency shifted output signal based upon the phase shifted current signal. One aspect of the present invention is that the phase shift block produces an output as a current signal and the mixer block is operably disposed and formed to receive the current signal produced by the phase shift block. Thus, the mixer includes a folded cascode mixer that provides a substantially low input impedance.

摘要： A Class AB voltage-to-current converter includes a plurality of DC coupled transconductance stages that produce a linearized output and a biasing circuit. The biasing circuit generates a primary bias voltage that is greater than a generated secondary bias voltage. As such, the first transconductance stage becomes active before the second transconductance stage with respect to the magnitude of a differential input voltage, thereby allowing the transconductance of the secondary transconductance stage to be added (or subtracted) from the transconductance of the primary stage to improve the overall transconductance of the Class AB voltage-to-current converter. As each of the plurality of transconductance stages is biased differently from the others, the various transconductance stages are biased on to differing amounts based upon the biasing signals as well as the input signal.
