    Abstract: Embodiments are directed to a system for measuring a degradation characteristic of a plurality of electronic components. The system includes a parallel stress generator communicatively coupled to the plurality of electronic components, and a serial electronic measuring component communicatively coupled to the plurality of electronic components. The parallel stress generator is configured to generate a plurality of stress signals, apply the plurality of stress signals in parallel to the plurality of electronic components and remove the plurality of stress signals from the plurality of electronic components. The serial electronic measuring component is configured to, subsequent to the removal of the plurality of stress signals, sequentially measure the degradation characteristic of each one of the plurality of electronic components in order to determine their degradation resulting from the applied stress signals.

    Abstract: Methods and systems for measuring a duty cycle of a signal include applying a first branch of an input signal directly to a latch. A delay of a second branch of the input signal is incrementally increased, with the second branch being applied to the latch, until the latch changes its output. A delay, corresponding to the latch's changed output, is divided by a period of the input signal to determine a duty cycle of the input signal.

    Abstract: Embodiments are directed to a system for synchronizing switching events. The system includes a controller, a clock generator communicatively coupled to the controller and a delay chain communicatively coupled to the controller. The delay chain is configured to perform a plurality of delay chain switching events in response to an input to the delay chain. The controller is configured to initiate a synchronization phase that includes enabling the clock generator to provide as an input to the delay chain a clock generator output at a synchronization frequency, wherein the clock generator output passing through the delay chain synchronizes the plurality of delay chain switching events to occur at the synchronization frequency resulting in a frequency of an output of the delay chain being synchronized to the synchronization frequency of the clock generator output.

    Abstract: A method of assembling a remote sensor system to detect a gas or chemical and a remote sensor system are described. The method includes fabricating a sensor, the sensor outputting a sensor signal that changes upon contact of the sensor with the gas or chemical and the sensor having an input port for a clock signal, coupling a capacitor to the sensor, the capacitor output voltage resulting from the sensor signal output by the sensor, and coupling a mixer to the capacitor and a low frequency oscillator, the mixer configured to mix the capacitor output voltage with the low frequency oscillator output to generate an output signal. The method also includes coupling an antenna to the mixer, the antenna configured to transmit the output signal indicating detection of the gas or chemical.
