US 12,719,415 B2 · Scalable periphery tunable matching power amplifier

Abstract

A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.

Dependent claims

An amplifier, comprising:

a plurality of transistors arranged in a stacked configuration;
and
a non-bypassing gate capacitor connected to a gate-terminal of a corresponding transistor of the plurality of transistors;
wherein:
the non-bypassing gate capacitor is configured to allow a first radio frequency (RF) voltage of the gate terminal of said corresponding transistor of the plurality of transistors to vary along with a second RF voltage at a drain terminal of said corresponding transistor of the plurality of transistors, thereby controlling a voltage drop across drain-source terminals of said corresponding transistor.
