    摘要: A novel self-supporting flat display screen based on thermionic emission of indirectly heated cathode structures (23, 30, 31, 32, 34; 230, 32, 34) is provided utilizing micro-filament heaters (21) that can be interconnected in any predetermined manner. The planar micro-filament (21) construction utilizes Dewer and Dewer-like techniques (10, 11, 12, 13, 14, 15) for controlling the thermal energy emitted and lowering the power consumption of a display device. Several control electrode techniques (42, 52, 33, 133, 142) are also incorporated in the invention to reduce the voltage levels required to control the display and simplify the overall electronic control circuitry needed by the display device. These techniques are combined to provide a high intensity, high contrast flat panel display using low voltage off-the-shelf electronic driver circuitry.

    摘要: A voltage-to current (V-to-I) converter circuit for use in combination with a current-controlled oscillator (ICO) to form a voltage-controlled oscillator (VCO), wherein the V-to-I converter circuit provides a current to the ICO while this current ranges itself corresponding to the process, supply voltage, and temperature needs of the ICO, thus allowing a more stabilized ICO and VCO. In one embodiment, the V-to-I circuit allows for independent adjustability to compensate for each quantity of required process, supply voltage, and temperature. In another embodiment, the V-to-I circuit includes compensation circuitry for process and temperature only. There is no need for supply voltage compensation because the supply voltage for the V-to-I converter circuit is provided from a supply that has been linearly regulated and preferably built-in on the chip.

    摘要: A current-controlled oscillator (ICO) circuit including an all p-channel transistor based ring oscillator, a first current mirroring stage, and a second current mirroring stage. The all p-channel transistor based ring oscillator, p-channel transistors in the input structure of each amplification stage, and metal lines in the ring and from the ring to the amplification stages over an n-well improve noise immunity and tolerance. The first current mirroring stage utilizes an input current to generate a first voltage controlling a series of differential delay cells connected in a ring topology that forms the ring oscillator. The second mirroring stage utilizes a precision current to generate a second voltage controlling at least one amplification stage, which converts corresponding delay cell output signals to a single-ended logic level signal compatible with external circuitry needs. Each amplification stages utilizes the second control voltage to create a similar or ratioed copy of the precision current flowing in each amplification stage. A second embodiment of the ICO is also included, which operates at a lower frequency, thus higher bandwidth, than that of the first embodiment.
