Abstract
A state machine in which the next state signals are biased by the next state encoder very close to the switch voltage of the input transistors of the present state latches to improve the response time of the state machine. Charge sharing on the outputs of the next state selector is prevented from affecting the biased next state signals by voltage substaining circuitry. By pre-encoding input signals pertinent to each state using separate input logic, the size of the next state selector is minimized, further improving the response time of the state machine. Selected present state latches may be prevented from changing state by gating the next state signals.
