Multi-channel power combiner with phase adjustment
Power combiners having increased output power, such as may be useful in millimeter-wave devices. The power combiner comprise at least two channels, wherein each channel comprises a phase alignment circuit, wherein the phase alignment circuit comprises a first differential input subcircuit comprising a first inverter and a second inverter, and a second differential input subcircuit comprising a third inverter and a fourth inverter, wherein the first inverter, the second inverter, the third inverter, and the fourth inverter each comprise a PMOS transistor and an NMOS transistor each having an adjustable back gate bias voltage. By adjusting the back gate bias voltage, the phases of the signal through each channel may be aligned, which may increase the output power of the power combiner. Methods of increasing output power of such power combiners. Systems for manufacturing devices comprising such power combiners.
