Designing Analog Circuits with Reduced Biasing Power

A new method is presented for the reduction of DC biasing power in nonlinear analog circuits. The key concept in this methodology is to remove the general biasing and replace it with "local biasing" of the individual devices in the circuit. The procedure limits the DC power consumption only to nonlinear devices for biasing purposes. The procedure makes these devices to respond to AC signals very much like linear components. It allows the circuit designer to chose his/her desired operating points for each device, independently and unaffected by the rest of the circuit.
