Patent number: 12254129Abstract: Examples are provided that relate to determining a capacitance based on a charge accumulated on a sense capacitor electrode. One example provides a head-mounted device comprising a facial-tracking sensor, a controller, and a charge sensing circuit connected to the facial-tracking sensor. The facial-tracking sensor includes a sense capacitor electrode configured to be positioned proximate to a surface of a face and form a capacitance based upon a distance between the sense capacitor electrode and the surface of the face, and the controller configured to apply a reference voltage to the sense capacitor electrode. The charge sensing circuit is configured to determine the capacitance of the sense capacitor electrode by determining an amount of charge accumulated on the sense capacitor electrode resulting from the reference voltage.Type: GrantFiled: June 28, 2022Date of Patent: March 18, 2025Assignee: Microsoft Technology Licensing, LLCInventors: Charles Walter Boecker, Jouya Jadidian, Barry Thompson, Niranjan Achugundla Puttaswamy, Lawrence Albert Prather

Patent number: 11936353Abstract: A current-mode transmitter amplifies a differential input signal to a differential, current-mode output signal. A split-input, current-mode-logic stage produces small, analog signals to limit switching currents and thus power consumption and power-supply noise. These small, analog signals are driven through a source-follower stage to reduce loading and shift the common-mode voltage to a desired level. A switched-current-source H-bridge driver combines differential outputs from the source-follower stage to provide an amplified differential output current. The output swing from the H-bridge driver is controlled by the voltage level from the source follower and derived from a replica-bias structure.Type: GrantFiled: July 22, 2019Date of Patent: March 19, 2024Assignee: Cadence Design Systems, Inc.Inventors: Eric Douglas Groen, Charles Walter Boecker

Patent number: 11770275Abstract: A PAM-4 DFE receives an input signal distorted by inter-symbol interference (ISI) and expressing a series of symbols each representing one of four pulse amplitudes to convey two binary bits of data per symbol. High-order circuitry resolves the most-significant bit (MSB) of each two-bit symbol, whereas low-order circuitry 115 resolves the immediate least-significant bit (LSB). An immediate value of the MSB is used to select a set of ISI offsets used to resolve the LSB. Resolved values of the prior values of the MSB and LSB are then used to select the ISI offset for the immediate symbol.Type: GrantFiled: June 28, 2022Date of Patent: September 26, 2023Assignee: Rambus Inc.Inventors: Masum Hossain, Nhat Nguyen, Charles Walter Boecker

Patent number: 11706060Abstract: A serial receiver combines continuous-time equalization, analog interleaving, and discrete-time gain for rapid, efficient data reception and quantization of a serial, continuous-time signal. A continuous-time equalizer equalizes a received signal. A number N of time-interleaved analog samplers sample the equalized continuous-time signal to provide N streams of analog samples transitioning at rate reduced by 1/N relative to the received signal. A set of N discrete-time variable-gain amplifiers amplify respective streams of analog samples. A quantizer then quantizes the amplified streams of analog samples to produce a digital signal.Type: GrantFiled: August 30, 2021Date of Patent: July 18, 2023Assignee: Rambus Inc.Inventors: Haidang Lin, Charles Walter Boecker, Masum Hossain
