    摘要: A current controlled field emission display includes a pair of pulsed transistors that charge and discharge capacitance within the field emission display. The capacitance may be a separate circuit element or may be the parasitic capacitance of the integrated transistors and related circuitry. Various circuit configurations are employed to control charge transfer to and from the capacitance. The control circuit is driven by a series of pulse pairs where the first pulse in each pair controls charging of the capacitance and the second pulse controls discharging of the capacitance through the emitter set.

    摘要: A waveshaping circuit for a sense amplifier pulldown device receives a standard digital signal at its input and independently creates a signal with two distinct rising slopes at its output. This unique output signal activates the sense amplifier pulldown device slowly at first with the first rising slope then quickly saturates it with the second rising slope allowing the sense amplifier to accurately sense and amplify the voltage difference between two digit lines.
