Abstract: In described examples, a multi-terminal switch includes first and second switches, and first, second, and third inductors. The first switch and first inductor are coupled between first terminals, the second switch and second inductor are coupled between second terminals, and the third inductor is coupled between third terminals. In a first mode, the first switch is opened and the second switch is closed. Opening the first switch and closing the second switch enables a first connection between the first terminals and the third terminals via a first magnetic coupling between the first and third inductors. In a second mode, the first switch is closed and the second switch is opened. Closing the first switch and opening the second switch enables a second connection between the second terminals and the third terminals via a second magnetic coupling between the second and third inductors.

Abstract: A frequency multiplier includes an input section having inputs to receive an input signal having an input frequency, a mixer section, and an output section magnetically coupled to the input section and generating an output signal in response to the input signal. The mixer section may be coupled to the input section by a common mode node forming a path for a common mode current to flow to the mixer section and be magnetically coupled to the common mode node. The input section may generate a signal current, and the mixer section may be magnetically coupled to the input section and be directly capacitively coupled to the input section through a capacitor in a signal current path. The mixer section may have differential inputs capacitively coupled to the input section and also be coupled to the input section through a current path. A current helper section may be coupled to the current path.

Abstract: In described examples, a method of operating a charge pump includes a first control signal deactivating a first transistor, and the first control signal's logical complement activating a second transistor to reset the first transistor's DC bias voltage. The first control signal's logical complement deactivates the second transistor, and the first control signal provides a bias voltage to the first transistor to activate it, causing current to be transmitted from an input voltage to an output terminal. A second control signal deactivates a third transistor, and the second control signal's logical complement activates a fourth transistor to reset the second transistor's DC bias voltage. The second control signal's logical complement deactivates the fourth transistor, and the second control signal provides a bias voltage to the third transistor to activate it, causing current to be transmitted from the output terminal to a ground.
