摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be used for detecting an incorrect clock frequency. In one example, the apparatus includes a first circuit configured to compare a clock signal period to a delay period. Additionally, in one example, the apparatus includes a second circuit configured to output a first signal. The period of the first signal may be double the clock signal period when the clock signal period is greater than the delay period. The apparatus may, in one example, also include a third circuit configured to output a second signal. The period of the second signal may be greater than double the clock signal period when the clock signal period is greater than the delay period.

摘要： Apparatus for sensing distributed load currents provided by power gating circuit. The apparatus includes a power gating circuit including a set of bulk transistors coupled in series with a set of circuits between first and second voltage rails. The apparatus includes a current sensor with a first ring oscillator, a first frequency-to-code (FTC) converter, a second ring oscillator, a second FTC converter, and a subtractor. The first ring oscillator includes a first set of one or more inverters configured to receive a first voltage at a node between the power gating circuit and the first circuit, and a second set of one or more inverters configured to receive a second voltage at a second node between the power gating circuit and the second circuit. The first ring oscillator is configured to generate a signal including a frequency related to the voltage drops across the first and second sets of transistors.
