Abstract: Quake Transistor Logic (QTL) circuits of the embodiments of the invention are low power, high-speed circuits that can be manufactured by the same process as the lower-speed complex circuits, and are thus capable of being integrated on the same device. A number of techniques are employed to give QTL circuits their unique advantages. Lower power without loss of speed is achieved through the use of a self-biasing clock buffer to eliminate the need for tail current sources in the logic; differential signals are employed throughout to improve noise immunity with a low logic signal swing; an optional tuning circuit provides extension of the frequency response to achieve an even higher clock frequency and logic circuit bandwidth.
