The document discusses a proposed new logic family called current-steering CMOS (CS-CMOS) that aims to reduce switching noise in mixed-signal systems.
[1] CS-CMOS is obtained through a simple modification to standard CMOS logic, adding a pair of complementary transistors to provide a constant bias current through the gate. This helps minimize noise generation during state transitions while keeping power consumption lower than other constant-current logic families.
[2] The static transfer characteristics of the CS-CMOS inverter are analyzed, showing it provides the same output high and low voltages as CMOS. Positive feedback is present due to the biasing transistors, leading to high gain during output transitions.
