Patent number: 11985831Abstract: An apparatus and configuring scheme where a ferroelectric capacitive input circuit can be programmed to perform different logic functions by adjusting the switching threshold of the ferroelectric capacitive input circuit. Digital inputs are received by respective capacitors on first terminals of those capacitors. The second terminals of the capacitors are connected to a summing node. A pull-up and pull-down device are coupled to the summing node. The pull-up and pull-down devices are controlled separately. During a reset phase, the pull-up and pull-down devices are turned on in a sequence, and inputs to the capacitors are set to condition the voltage on node n1. As such, a threshold for the capacitive input circuit is set. After the reset phase, an evaluation phase follows. In the evaluation phase, the output of the capacitive input circuit is determined based on the inputs and the logic function configured during the reset phase.Type: GrantFiled: December 15, 2021Date of Patent: May 14, 2024Assignee: Kepler Computing Inc.Inventors: Amrita Mathuriya, Rafael Rios, Ikenna Odinaka, Rajeev Kumar Dokania, Debo Olaosebikan, Sasikanth Manipatruni

Patent number: 11979148Abstract: Asynchronous circuit elements are described. Asynchronous circuit elements include a consensus element (c-element), completion tree, and validity tree. The c-element is implemented using adjustable threshold based multi-input capacitive circuitries. The completion tree comprises a plurality of c-elements organized in a tree formation. The validity tree comprises OR gates followed by c-elements. The multi-input capacitive circuitries include capacitive structures that may comprise linear dielectric, paraelectric dielectric, or ferroelectric dielectric. The capacitors can be planar or non-planar. The capacitors may be stacked vertically to reduce footprint of the various asynchronous circuitries.Type: GrantFiled: January 14, 2022Date of Patent: May 7, 2024Assignee: Kepler Computing Inc.Inventors: Amrita Mathuriya, Nabil Imam, Ikenna Odinaka, Rafael Rios, Rajeev Kumar Dokania, Sasikanth Manipatruni

Patent number: 11978762Abstract: A configuration for efficiently placing a group of capacitors with one terminal connected to a common node is described. The capacitors are stacked and folded along the common node. In a stack and fold configuration, devices are stacked vertically (directly or with a horizontal offset) with one terminal of the devices being shared to a common node, and further the capacitors are placed along both sides of the common node. The common node is a point of fold. In one example, the devices are capacitors. N number of capacitors can be divided in L number of stack layers such that there are N/L capacitors in each stacked layer. The N/L capacitors are shorted together with an electrode (e.g., bottom electrode). The electrode can be metal, a conducting oxide, or a combination of a conducting oxide and a barrier material. The capacitors can be planar, non-planar or replaced by memory elements.Type: GrantFiled: March 14, 2022Date of Patent: May 7, 2024Assignee: KEPLER COMPUTING INC.Inventors: Rajeev Kumar Dokania, Amrita Mathuriya, Debo Olaosebikan, Tanay Gosavi, Noriyuki Sato, Sasikanth Manipatruni

Patent number: 11967954Abstract: A class of complex logic gates are presented that use non-linear polar material. The logic gates include multi-input majority gates. At least one input to an individual multi-input majority gate is a fixed input. Other inputs are driven to non-linear input capacitors on their respective first terminals. The second terminals of the non-linear input capacitors are coupled a summing node, which provides a majority function of the inputs. The summing node is coupled to a CMOS logic. Leakage through the capacitors is configured such that capacitors of a majority gate have substantially equal leakage, and this leakage has a I-V behavior which is symmetric. As such, reset device(s) on the summing node are not used. The non-linear charge response from the non-linear input capacitors results in output voltages close to or at rail-to-rail voltage levels, which reduces the high leakage problem faced from majority gates that use linear input capacitors.Type: GrantFiled: April 20, 2022Date of Patent: April 23, 2024Assignee: KEPLER COMPUTING INC.Inventors: Amrita Mathuriya, Rafael Rios, Ikenna Odinaka, Darshak Doshi, Rajeev Kumar Dokania, Sasikanth Manipatruni

Publication number: 20210228081Abstract: Processes, scales, and devices to measure and quantify wetness perception in humans. Exemplary devices and scales utilize sensor fusion of temperature and pressure modalities, for which humans have dedicated receptors in the skin, to understand how the perception of wetness comes about. Processes test the utility of wetness perception as a biomarker for assaying peripheral neuropathy. Wetness perception devices include a Peltier module. The temperature of the Peltier module can be varied precisely using a computer-aided feedback system, mounted on a load scale to enable concomitant pressure measurements. Devices may include an insulation chamber with desiccators in place to lower internal humidity and prevent condensation. Wetness perception can be used as a non-invasive biomarker for disease-related peripheral neuropathy in which sensory mechanisms are disrupted.Type: ApplicationFiled: December 3, 2020Publication date: July 29, 2021Inventors: Sandhya Kumar, Surabhi Kumar, Amrita Kumar
