Abstract
A power amplifier circuit includes N (N is an integer equal to or greater than 2) power amplifier circuit cores, which in operation, amplify power of an input signal, N inductors, which in operation, are connected to the N power amplifier circuit cores, and ring-oscillator-type transconductance (gm) generation circuitry, which in operation, generates transconductance (gm) for compensating power loss of the N inductors.
