    Abstract: Clock tree design methods for ultra-wide voltage range circuits are disclosed. In one aspect, place and route software creates an integrated circuit (IC) in an optimal configuration at a first voltage condition. A first clock tree is created as part of the place and route process. Clock skew for the first clock tree is evaluated and minimized through insertion of bypassable delay elements. The delay elements are then removed from the wiring routing diagram. A second voltage condition is identified, and clock tree generation software is allowed to optimize the wiring routing diagram for the second voltage condition. The second clock tree generation software may insert more bypassable delay elements into the wiring routing diagram that allow clock skew optimization at the second voltage condition. The initial bypassable delay elements are then reinserted into the wiring routing diagram and a finished IC is established.

    Abstract: Methods and apparatus for identifying a process corner are provided. Provided is an exemplary method for identifying a process corner of an integrated circuit (IC). The IC has a first asymmetrical ring oscillator (ARO1) including pull-up transistors that have a low threshold voltage (LVT) and pull-down transistors that have a regular threshold voltage (RVT), and has a second asymmetrical ring oscillator (ARO2) including pull-up transistors that have an RVT and pull-down transistors having an LVT. The exemplary method includes applying an ultra-low power supply voltage to the ARO1 and the ARO2 that causes the integrated circuit to operate near a verge of malfunction, measuring an output frequency of the ARO1, measuring an output frequency of the ARO2, calculating a calculated ratio of the output frequency of the ARO1 and the output frequency of the ARO2, and comparing the calculated ratio to a fiduciary ratio to identify the process corner.

    Abstract: Electronic devices employing adiabatic logic circuits with wireless charging are disclosed. In one aspect, an electronic device is provided. The electronic device includes a power circuit employing an alternating current (AC) coupler circuit configured to receive a wireless AC signal and generate a wired AC signal based on the wireless AC signal. The power circuit includes a power output configured to provide an AC power signal based on the wired AC signal generated by the AC coupler circuit. The AC power signal is generated based on the wireless charging capability of the AC coupler circuit. The electronic device employs a digital logic system that includes a power rail electrically coupled to an adiabatic logic circuit. The AC power signal is provided to the power rail to provide power to the adiabatic logic circuit. Wirelessly charging the adiabatic logic circuit consumes less power than conventional non-wireless charging circuitry.

    Abstract: Clock distribution schemes with wide operating voltage ranges are disclosed. In one aspect, an operating voltage level or condition within a computing device is sensed. In a first voltage condition, delay elements are used within a clock tree to minimize clock skew. In a second voltage condition, one or more delay and/or clocked elements are bypassed to minimize clock skew at the second voltage condition. In addition to controlling clock skew, power may be conserved by depowering the bypassed elements. Controlling clock skew in this fashion improves operation of a computing device that includes the clock tree and may improve battery life.
