ABSTRACT:
A pair of differentially related currents are caused to flow in a pair of current modes. A symmetrical current mirror is coupled to the nodes and level shifting means coupled from each node to the current mirror common terminal. A pair of output transistors have their bases directly coupled to the nodes and their emitters cross coupled to the same nodes so that when the nodes are driven to a one V.sub.BE differential, output collector current will flow. The output transistors have their collectors commonly coupled to the circuit output. Deadband control means are connected to the current mirror common terminal so that no output current will flow until the deadband differential is exceeded.
