<p>The amplifier has a small signal gain characteristic which is linear and independent of device temperature. The amplifier includes at least two further transistors (Q3, Q4) than known types of amplifiers constituting a bipolar circuit using emitter coupled pairs. A further transistor (Q3, Q4) is serially connected to a respective emitter of an existing transistor (Q1, Q2) in the emitter coupled pair. The respective bases of the further transistors are cross-connected to the emitter of the existing transistor in the opposite leg of the pair. The amplifier may also be provided with a level shifting circuit and a matched level shift circuit (Q5, Q6, D1, D2).</p> |
