Abstract
The invention concerns an electronic circuit which corrects for non-linearities present in transistor devices. The inventive circuit allows for the construction of amplifiers that are inherently low in distortion, eliminating the requirement for the use of feedback to linearize the amplifier. The invention is particularly useful for driving audio amplifiers, but can be used with other audio devices and amplifiers. The circuit has an input transistor connected in tandem with a second transistor. The transistor pair functions as a unit to cancel the log varying base-emitter resistance of the input transistor, while also canceling the base-emitter temperature drift of the input transistor.
