  • Patent number: 10996266
    Abstract: Circuits and methods for testing voltage monitor circuits are provided. In an embodiment, an integrated circuit (IC) includes power management unit (PMU), a set-reset (S-R) latch circuit, a multiplexer, and an AND gate circuit. A voltage monitor circuit of the PMU generates an output signal based on a difference between a received reference voltage and a received sense voltage from a functional supply. A power on reset (PoR) generator of the PMU generates a PoR signal based on a power up condition of the PMU. The S-R latch circuit generates an enable signal based on the output signal of the comparator circuit and the PoR signal. The multiplexer passes-through the output signal of the comparator circuit during a functional condition of the PMU. The AND gate circuit generates an enable signal based on an output of the multiplexer and an output of the S-R latch circuit.

  • Patent number: 10771082
    Abstract: An analog-to-digital converter includes a sampling capacitor connected to a multiplexer output, discharge circuitry discharging the sampling capacitor during a first period beginning at a start of a sampling cycle, and level shifting circuitry charging the sampling capacitor to a voltage at a first analog input node modified by a mismatch voltage resulting from mismatch in threshold voltages between a first transistor connected to the first analog input node and a second transistor connected to the output node, during a second period beginning at expiration of the first period. A first switch connects the first analog input node to the output node to charge the sampling capacitor to the voltage at the first analog input node, at expiration of the second period, and disconnects the first analog input node from the output node at an end of the sampling cycle of the analog-to-digital converter.

  • Patent number: 10680587
    Abstract: An RC oscillator generates a periodic trigger signal, and a clock generator generates clock edges in response.

The RC oscillator includes first and second comparison circuits, a logic circuit receiving output from the first and second comparison circuits and generating the periodic trigger signal, and a clock generation circuit generating a clock signal therefrom. The stuck-at-fault detection circuit includes a capacitive node, charge circuitry charging the capacitive node based upon the periodic trigger signal, discharge circuitry discharging the capacitive node based upon the periodic trigger signal, and triggering circuitry asserting a reset signal to cause the RC oscillator to reset when the charge on the capacitive node indicates a stuck-at-logic state of the periodic trigger signal.

  • Patent number: 10651641
    Abstract: A circuit includes an input terminal and a regulated supply line for supplying an electronic device with an electrostatic discharge protection and driver circuit for the electronic device. The supply line is coupled to the input terminal via the circuitry, so that current injected into the input terminal may produce a voltage increase on the regulated supply line. A comparator sensitive to the voltage at the input terminal and the voltage on the supply line is provided. A current sink coupled with the supply line and being activatable to sink current from the supply line is also provided. The comparator is configured for activating the current sink as a result of the voltage at the input terminal exceeding the voltage on the supply line of a certain intervention threshold.
