Disclosed are example embodiments of methods and systems for calibrating the second and third order intermodulation intercept points of a radio transceiver. The calibration circuit comprises: a common mode voltage (VCM) calibration circuit having a complementary to absolute temperature (CTAT) voltage node coupled to one or more VCM nodes of the radio transceiver, wherein the VCM calibration circuit is configured to adjust the CTAT voltage to reduce a third-order intermodulation (IM3) at an output of the radio transceiver; and a bulk terminal calibration circuit configured to bias one of a VBP and VBN voltages at one or more bulk terminals of one or more transistors of the RF circuit to reduce a second-order intermodulation (IM2).
