摘要： Threshold logic gates using flash transistors are provided. In an exemplary aspect, flash threshold logic (FTL) provides a novel circuit topology for realizing complex threshold functions. FTL cells use floating gate (flash) transistors to realize all threshold functions of a given number of variables. The use of flash transistors in the FTL cell allows a fine-grained selection of weights, which is not possible in traditional complementary metal-oxide-semiconductor (CMOS)-based threshold logic cells. Further examples include a novel approach for programming the weights of an FTL cell for a specified threshold function using a modified perceptron learning algorithm.

摘要： Threshold logic elements and methods of operating the same are disclosed. In one embodiment, a threshold logic element includes a first input gate network configured to receive a first set of logical signals, a second input gate network configured to receive a second set of logical signals. The differential sense amplifier is operably associated with the first input gate network and the second input gate network such that the differential sense amplifier is configured to generate a differential logical output in accordance with a threshold logic function. In order to make the threshold logic element more robust, the differential sense amplifier is configured to feed back the differential logical output to the first input gate network and the second input gate network. By providing the differential logical output as feedback, floating node issues are avoided and the threshold logic element is more resistant to noise.

摘要： A circuit and method for calibrating CMOS (complementary metal-oxide semiconductor) inverters are provided. In a circuit, a first tunable CMOS inverter, controlled by a control signal, receives a first voltage from a first circuit node and outputs a second voltage to a second circuit node. A second tunable CMOS inverter, controlled by the control signal, receives the second voltage from the second circuit node and outputs the first voltage to the first circuit node. A resistor couples the first circuit node to the second circuit node. A switch, controlled by a reset signal, conditionally shorts the first circuit node to the second circuit node. A finite state machine receives the first voltage and the second voltage and outputs the reset signal and the control signal, wherein the control signal is adjusted based on a difference between the first voltage and the second voltage.
