Energy constrained RF transceivers for mobile wireless communications

Several new approaches are presented for the reduction of power dissipation in wireless transceivers for mobile wireless applications. In most cases, the power dissipation of the circuit can be dramatically lowered without a significant reduction in circuit dynamic range or linearity. These techniques involve the use of active bias circuits to continuously optimize the performance of the circuit under varying bias levels.
