Techniques are described for monitoring and controlling a bias current of the amplifier. In one exemplary design, an apparatus may comprise an amplifier and a bias circuit. The amplifier may include at least one transistor coupled to the inductor ring. Bias circuit to generate at least one bias current for the at least one transistor of the amplifier, it is also possible to obtain a target bias current for the amplifier. Biasing circuit voltage across the inductor of the amplifier, or at least one of the one gate of the at least one transistor of the current mirror, or an amplifier formed as one of the transistors of the amplifier-to-source voltage, or the voltage at the replica circuit replicating the amplifier, or a switched mode power supply may also generate the at least one bias voltage on the basis of the current applied to the amplifier in the disabled state.
