Abstract
To reduce the wasted power with using an OP-AMP, 3 circuit supplying the same amount of power to load through overall voltage range can able proposed. With this type of design, the power that induced to the devices in the circuit will be reduced, we can also develope a small size power supply with the OP-AMP developed using this design. If we need a OP-AMP needed to handle higher power than usual, another design technique can be proposed. With substituting one device with the devices connected in series, the power loaded to each devices in the series devices can be reduced. This thesis contents the design of an OP-AMP to use in high power fields with small thermal dissipation.
