  • Publication number: 20200036339
    Abstract: A power amplifier circuit includes a coil circuit, a differential amplifier and a diverting current path. The coil circuit includes first and second coil portions coupled to a common node. The differential amplifier includes first and second transistors, each of which has first, second and third terminals. The respective first terminals of the first and second transistors are coupled to the coil circuit, and the respective third terminals of the first and second transistors are coupled to a ground terminal. The diverting current path is coupled between the common node and the ground terminal to divert portions of perturbation currents caused by a biasing voltage with a time varying magnitude at the second terminals of the first and second transistors. The diverting current path provides relatively high admittance path between the first terminals of the first and second transistors and ground, thereby reducing perturbation currents that exit the third terminals.
