ABSTRACT:
A transmission circuit including cross coupled transistors is described. The circuit is symmetrical and the base of each transistor is coupled to the collector of the other and also to a supply voltage through a voltage divider. The output is taken across the emitters of the transistors. Switching circuits which are coupled to the voltage dividers change the resistance of the circuit and effect an output signal. The symmetrical configuration of the circuit and the cross coupling make the circuit insensitive to temperature changes.
