Abstract

An electronic circuit and method are provided. The electronic circuit includes an in-phase (I)-quadrature (Q) amplifier including an I cascode branch and a Q cascode branch, the IQ amplifier configured to receive a differential input and control signals, control, based on the control signals, gate voltages in the I cascode branch and gate voltages in the Q cascode branch, generate an I output signal with the I cascode branch, and generate a Q output signal with the Q cascode branch, and a quadrature coupler configured to perform quadrature summation of the I output signal and the Q output signal and generate a final phase shifted output.
