ABSTRACT:
An improved BiCMOS logic circuit utilizes an emitter-coupled pair of bipolar transistors for differentially comparing an input signal with a logic reference level. Each of the bipolar transistors are resistively loaded by a network of p-channel metal-oxide-semiconductor (PMOS) transistors coupled in parallel. At least one of the parallel combination of transistors has its gate coupled to a control signal providing a variable load resistance. The control signal is preferably provided by a feedback network which maintains a constant voltage swing across the network over temperature.
