Abstract: A voltage-variable capacitor having a relatively high figure of merit, Q, and thus useful at relatively high frequencies, includes a thin layer of epitaxial semiconductive material on a highly doped semiconductor substrate. An apertured dielectric layer is disposed on the epitaxial layer and a layer of material capable of making rectifying contact to the semiconductive material is disposed on the dielectric layer, with a portion thereof extending into an aperture in the dielectric layer into rectifying contact with the epitaxial layer. This construction eliminates the need for a diffused, minority-carrier-collecting junction, thereby allowing the epitaxial layer to be thin and the series resistance of the device to be low.

Abstract: A comb filter comprising a charge transfer device (CTD) structure for separating frequency interleaved luminance and chrominance components of a composite color television signal directly within the CTD structure. The CTD structure has first and second pairs of input sections of substantially identical geometry, one input section of the second pair being preceded by a signal inverter. Signal charge as applied to the first and second input pairs are delayed such that signal charge from the first input pair exhibits a 1H delay relative to signal charge from the second input pair, when the signal charge from the respective input pairs are combined with each other. A first charge summing well combines mutually in-phase signal charge at multiples of the line scanning frequency from the first and second inputs to provide a combed luminance signal charge component, while a second well combines mutually inverted or out-of-phase signal charge at these frequencies from the first and second inputs to provide a combed chrominance signal charge component.

Abstract: DIGITAL MEMORY ADDRESSING SYSTEM A digital memory may be addressed with an analog signal utilizing a circuit comprising a digital to analog converter. A comparator compares the output of the digital to analog converter to the analog address signal. The output of the comparator is coupled to means for incrementing and decrementing a digital number in response to that output. The digital number incrementing and decrementing means has an output which is coupled to the addressing input of the digital memory. Switch means alternately connects the input of the digital to analog converter to either the output of the random access memory or the output of the means for changing the digital number.

Abstract: An insulated gate field effect transistor adapted for use at high frequencies, with usable gain within a broad range of frequencies, includes a plurality of dual gate MOS transistor unit structures, each with good characteristics for high frequency operation, interconnected in parallel on a single semiconductor body. The parallel combination provides a relatively high ratio of transconductance to output load capacitance and the gain bandwidth product of the device is therefore relatively high. The unit structures are formed in a substrate region including a ground plane. The means for interconnecting the unit structures in parallel includes a diffused region for connecting one gate electrode of each unit to the corresponding gate electrode of the others. This diffused region lies close to each unit structure to provide a local capacitive high frequency by-pass to ground. Low capacitance beam leads for connecting the device to external circuitry further reduce output loading capacitances.
