POWER AMPLIFICATION CIRCUIT

摘要

Disclosed is a power amplification circuit wherein linearity and power efficiency are improved. The power amplification circuit is provided with: a first transistor, which amplifies signals inputted to a base, and outputs amplified signals from a collector; and a first capacitor, which is provided between the base and the collector of the first transistor, and which has an electrostatic capacitance having a voltage dependency lower than that of a parasitic capacitance between the base and the collector of the first transistor.
