Abstract
A common emitter amplifier having a resistor in series with its emitter and a resistor in series with its collector is temperature stabilized by providing a current source in parallel with the resistor in series with the collector. The current source provides additional emitter current to the transistor to decrease the transistors internal AC emitter resistance. Cascoded transistors are also used to improve the performance of the amplifier.
