ABSTRACT:
A monolitic transistor amplifier includes a negative feedback network between the output stage and an input stage. The network comprises one or more resistive voltage divider L-link with shunt elements which have a higher temperature coefficient than its series elements. The shunt elements have resistors which are in close thermal contact with the output transistor causing the negative feedback to increase with the current passing the output transistor. The shunt resistors are formed in the collector diffusion giving them a temperature coefficient of 3.5%/.degree. C.
