摘要： A multiple-valued literal circuit is implemented with resonant tunneling diodes (RTD). A number of RTD sections are connected in series with a current source. Current is tapped by a current bleeder between every two adjacent RTD sections. The current bleeders are turned on at different levels of input voltage, which is applied at the joint between the current source and the RTD sections. When the voltage reaches a certain threshold level, the current bleeder with the highest threshold voltage is turned on and taps the most current from the current source, depleting the current from other current bleeders with lower threshold voltages. Thus only one dominant current is tapped from the current source. The literal circuit can be used for multiple-valued decoders, multiplexers, demultiplexers and other multiple-valued digital systems.

摘要： A multi-channel electronic visual aid device which is able to signal to the user whether sound is coming from the left or right, front or back, or both. For the plurality of channels, which may operate in pairs, the sound is picked up by a respective microphone and amplified and rectified into a DC voltage. The DC voltage is next fed to an analog to digital converter and then to a digital encoder. The binary code from the encoder is coupled into a logic circuit where the binary code is decoded to provide a plurality of output levels which are used to drive an indicator which, in turn, provides a visual indication of the sound level received. The binary codes for each pair of channels are also fed into a digital comparator. The output of the comparator is used to enable the logic circuits of the two channels such that if, for example, the signal coming from the right is louder than that coming from the left, the output of the logic unit of the right channel will be enabled and the corresponding indicator activated, indicating the sound source on the right. An indication of the loudness is also provided. One embodiment of the invention may be carried by the hearing impaired or deaf, as a system, for example, which is embedded into eye glasses or a cap. Another embodiment of the invention may be integrated with a vehicle to give a hearing impaired or deaf driver a warning, with a directional indication, that an emergency vehicle is in the vicinity. In this second embodiment, the emergency vehicle transmits an RF signal which would be used as an enabling signal for the visual aid device to avoid false alarms from traffic and other sound sources in the vicinity of the dirver's vehicle.

摘要： A method of simulating the voltage-current characteristics of a short channel metal-oxide-semiconductor field effect transistor (MOSFET) by connecting a series of incremental MOSFETs of different threshold voltages. The threshold voltages near the source and the drain are reduced due to charge sharing. The substrate of each reduced threshold voltage incremental MOSFET is connected to its source. The reduction in threshold voltage can be obtained by Schwartz-Christoffel transformation of the depletion layer edges of the charge sharing region. From these threshold voltages one can calculate the incremental channel conductances and the voltage drops.

摘要： The folding V-I characteristic of a resonant tunneling diode (RTD) is utilized to generate the multiple membership functions for each antecedent. The folding characteristic of an RTD generally has a triangular shape, which corresponds to the popular membership function functions commonly in use. The amount of overlap of adjacent membership functions can be adjusted by adding or substracting a dc current to or from the RTD characteristic. The use of RTD folding characteristic to generate multiple membership functions can be used in a fuzzifier to simplify circuit implementation. A time varying membership function can be generated by sweeping the RTD with a voltage ramp. This time varying membership function can be used in the defuzzifier to obtain a crisp output.

摘要： A pair of n-peaked resonant tunneling diodes with series resistance are connected in series across a supply voltage to form a digitizer, which has 2n+1 stable operating points. There are n high current operating points and n+1 low current operating points, corresponding to "1" and "0" logic levels. For an n-bit analog-to-digital converter, the analog input voltage is divided into n binary-weighted fractions and applied to n digitizers, which latch the divided voltages into binary currents serving as digital output.

摘要： The proposed general-purpose, fully-analog device is capable of such functions as auto-correlation, cross-correlation, convolution, transversal filters, etc. at high speeds (one megahertz typical sample rates) with no analog-to-digital or digital-to-analog conversions. The device correlates analog samples in one CCD channel against analog samples in a second CCD channel by means of balanced MOSFET's which multiply the associated voltage samples to give current products that are summed for all multipliers. The two CCD channels include unique floating-clock sensor and buffer circuits which sense the CCD charge samples without affecting the efficiency of their propagation along the CCD shift register. The matched MOSFET multipliers and current summing amplifiers are also uniquely combined in a dual-differential configuration so as to minimize the nondestructive sensing and buffering cells and the matched multiplier cells with the longitudinal dimensions of the CCD, permitting the latter to be small for efficient propagation.
