Abstract: A stacked transformer or inductor apparatus including a first layer with a first layer wire element extending around a center axis and a second layer with a second layer wire element. The second layer element includes side by side first and second wire components in parallel spaced relation extending around the center axis and the first wire component is connected to the first layer wire element to form a primary turn winding. A third layer includes a third layer wire element extending around the center axis and connected to the second wire component of the second layer wire element to form a secondary turn winding partially overlapping with the primary turn winding.

Abstract: A method for harmonic trapping in a matching network of a power amplifier includes determining primary inductance and secondary inductance of a differential transformer of the matching network, based on a signal operating frequency of the power amplifier. An inductance value for an L-C filter is determined based on the secondary inductance and a harmonic frequency of a local oscillator (LO) signal. A capacitance value for the L-C filter is determined based on the inductance value and the harmonic frequency of the LO signal. The L-C filter is provided on an electric connection between a direct current (DC) bias voltage source and a secondary inductor of the differential transformer. The L-C filter is configured with the determined inductance value and the determined capacitance value.

Abstract: Techniques are provided for fanning out a signal from a balun. In various aspects, the system can include a balun configured to receive a signal for transmission at an input and to provide a representation of the signal at an output, a plurality of pass gate circuits, each pass gate circuit configured to receive the representation of the signal at a first node, to receive a control signal at a second node to pass the representation of the signal to a third node when the control signal is in a first state, and to isolate the representation of the signal from the third node when the control signal is in a second state. The first state of the control signal can include a non-zero voltage, and the second state of the control signal can include the non-zero voltage with a polarity opposite the non-zero voltage of the first state.

Abstract: An on-chip transformer circuit is disclosed. The on-chip transformer circuit comprises a primary winding circuit comprising at least one turn of a primary conductive winding arranged as a first N-sided polygon in a first dielectric layer of a substrate; and a secondary winding circuit comprising at least one turn of a secondary conductive winding arranged as a second N-sided polygon in a second, different, dielectric layer of the substrate. In some embodiments, the primary winding circuit and the secondary winding circuit are arranged to overlap one another at predetermined locations along the primary conductive winding and the secondary conductive winding, wherein the predetermined locations comprise a number of locations less than all locations along the primary conductive winding and the secondary conductive winding.
