Abstract
Embodiments of the present disclosure provide a transmitter system including: a source follower (SF) sub-stage having a pair of transistors, one being coupled to a biasing voltage at a gate terminal thereof, and the other including a fully depleted semiconductor on insulator (FDSOI) transistor coupled to an input signal at a gate terminal thereof, and coupled to a calibration voltage at a back-gate terminal thereof. A mixer sub-stage includes a mixer input node coupled to the SF output node of the pair of transistors of the SF sub-stage, and the mixer input node is electrically coupled in parallel to two FDSOI mixer transistors, with the FDSOI mixer transistor being electrically coupled to a respective back-gate voltage. The FDSOI mixer transistors each include a gate terminal coupled to an input voltage, while a second source/drain terminal of the FDSOI mixer transistors are each electrically coupled to a mixer output node.
