| Summary: | In this paper, a new method is proposed which renders possible shifting of the optimum operating point for total harmonic distortion to any desired point on the do transfer characteristic of active-loaded bipolar junction transistor amplifiers, by incorporating an additional current source into the circuit to obtain different do current levels in driver and load transistors. A new analytical expression is derived to calculate the amount of additional current. Furthermore, two new circuit topologies are introduced for harmonic distortion reduction, which will be used according to the flow direction of the additional current. |
