Abstract:
A current mode power amplifier includes a current steering stage configured to steer a scaled current based on differential voltage inputs, a filtered current mirror connected to the current steering stage to receive the scaled current and produce a filtered output current, and a resonant load configured to receive the output current and generate an output voltage signal for transmission.
