System and method for providing isolation of bias signal from RF signal in integrated circuit

An integrated circuit comprising:

• a first transistor device having first, second, and third terminals;
• a first inductor;
• a first bypass capacitor spaced apart from the first inductor by a first region extending a first distance along a first direction between the first bypass capacitor and the first inductor;
• and
• a first transmission line segment,
• wherein the first transmission line segment includes first and second ends and extends between the first and second ends,
• wherein the first end is at least indirectly coupled to the first bypass capacitor and the second end is at least indirectly coupled to a first additional end of the first inductor,
• wherein the first transmission line segment is configured to impart a non-negligible phase shift to a signal communicated between the first and second ends, or is configured to have a non-negligible effective inductance, and
• wherein at least one of the first, second, and third terminals of the first transistor device is coupled at least indirectly to the first inductor.

A power amplification system comprising:

• an RF input terminal;
• a peak amplifier RF integrated circuit coupled at least indirectly to the RF input terminal;
• a carrier amplifier RF integrated circuit coupled at least indirectly to the RF input terminal,
• wherein either the peak amplifier RF integrated circuit or the carrier amplifier RF integrated circuit includes:
• a first transistor device having first, second, and third terminals;
• a first inductor;
• a first bypass capacitor spaced apart from the first inductor by a first region extending a first distance along a first direction between the first bypass capacitor and the first inductor;
• and
• a first transmission line segment having first and second ends and at least indirectly coupling the first inductor and the first bypass capacitor,
• wherein the first transmission line segment is configured to have a non-negligible effective inductance, and has an electrical length between the first and second ends that is sufficient to impart a non-negligible signal delay to a signal communicated between the first and second ends.
