摘要： Techniques for on-chip detection of integrated circuit power supply noise are disclosed. By way of example, a technique for monitoring a power supply line in an integrated circuit comprises the following steps/operations. A first signal and a second signal are preconditioned. The first signal is representative of a voltage of the power supply line being monitored. The second signal is representative of a voltage of a reference power supply line. Preconditioning comprises shifting respective levels of the voltages such that the voltages are within an input voltage range of comparator circuitry. Then, the preconditioned first signal and the preconditioned second signal are compared in accordance with the comparator circuitry. Comparison comprises detecting when a difference exists between the voltage level of the preconditioned first signal and the voltage level of the preconditioned second signal.

摘要： A device temperature measurement circuit, an integrated circuit (IC) including a device temperature measurement circuit, a method of characterizing device temperature and a method of monitoring temperature. The circuit includes a constant current source and a clamping device. The clamping device selectively shunts current from the constant current source or allows the current to flow through a PN junction, which may be the body to source/drain junction of a field effect transistor (FET). Voltage measurements are taken directly from the PN junction. Junction temperature is determined from measured junction voltage.

摘要： A method and circuit for static phase error measurement includes a reference clock delay chain having a selectable number of delay elements. A number of the delay elements are enabled in accordance with a select length signal to delay a reference clock signal. A feedback signal delay chain also has a selectable number of delay elements. A number of the delay elements are enabled in accordance with a select length signal to delay a feedback signal. A latch tests phase alignment between the delayed reference clock signal and the delayed feedback signal and outputs a measurement of static phase error.
