Abstract
A pulse logic circuit comprises a plurality of interconnected stages. Each of the stages includes a relatively large node-charging transistor which, when enabled, forwards charging current to a node from a timing pulse of one of a plurality of phases applied to a load capacitance in series with the node-charging transistor. Such large transistors exhibit significant gate-to-source and gate-to drain distributed capacitances. The response time for charging a selected stage node can be decreased by precharging the gate of the node-charging transistor of a selected stage to enable the transistor prior to the application of a timing pulse, thereby increasing the maximum operating speed of the circuit. Disclosed species of such a pulse logic circuit include time vernier circuits which can be utilized as control circuitry for a liquid crystal television or computer display.
