<p>A differential amplifier (12, 14) including circuit means (20, 20) for generating a tail current which is not only proportional to absolute temperature, but also is adjusted to compensate for the non-ideal transistor geometries and properties, including finite beta and non-zero, temperature-dependent intrinsic resistances, so as to result in an amplification ratio which is substantially independent of all component variations.</p> |
