Abstract
A linear bipolar junction transistor amplifier. The linear gain is achieved by an offset voltage created by ratioed transistors wherein the ratio is an integer. The ratios are achieved either by connecting equal transistors in parallel or by employing multiple emitters on a single transistor. This results in a linear amplifier which is substantially independent of manufacturing process tolerance variations as well as power supply and temperature variations.
