摘要： A delay line of individually selectable delay elements can operate as an oscillator in an open loop mode to track process variation or drive a clock signal that varies with temperatures and voltages in the system. The delay line oscillator can also operate in a closed loop mode to match a frequency given by a tuner ratio and a reference clock. The delay line can also be used for measuring clock jitter or duty cycle.

摘要： An apparatus of one embodiment includes a sensor and a controller. The sensor has first and second electrodes separated by an insulator. The controller includes measurement circuitry, a processor, and a memory comprising logic. The logic is operable to disconnect the second electrode from the measurement circuitry, induce a current on the second electrode by applying voltage to the first electrode, apply charge to the second electrode, connect the second electrode to the measurement circuitry after applying the charge to the second electrode, and determine a capacitance value associated with the second electrode.

摘要： An apparatus comprises a comparator that includes a first input, a second input and an output. The comparator is configured for measuring a difference in voltage between a source coupled to the first input and another source coupled to the second input, and providing information associated with the measured difference at the output. The apparatus also comprises a controllable current source coupled to the first input of the comparator and configured for supplying or drawing current. The apparatus also comprises a digital logic circuit that is configured for controlling an amount of current supplied or drawn by the controllable current source. The apparatus is configured for measuring a charge associated with an external source that is coupled to the first input of the comparator.
