  • Patent number: 10763833
    Abstract: In described examples, a ring oscillator includes a series of N stages in a first ring. Each stage includes a respective output terminal coupled to a respective input terminal of a next one of the stages in the first ring. N is a positive odd-numbered integer of at least three. A series of N level shifters in a second ring are respectively connected to the N stages. Each level shifter receives a respective clock output from a respective output terminal of a stage to which it is connected and generates a respective boosted clock output in response thereto. The boosted clock output is coupled to control an impedance state of a next one of the level shifters in the second ring.

  • Patent number: 10545752
    Abstract: An integrated circuit including a ferroelectric random access memory (FRAM) for storing firmware, and a method of updating that firmware. The FRAM is constructed to selectively operate as a 2T2C FRAM memory in a normal operating mode, and as a 1T1C FRAM memory in an update mode. Updating of the stored firmware is performed by placing the FRAM in its update (1T1C) mode and writing the updated code into alternate rows of the 1T1C half-cells at each of a plurality of memory locations, while the other 1T1C half-cells in the other alternate rows retain the original data. Following verification of the updated contents, the original data in the other half-cells are overwritten with the verified updated data, and the operating mode is changed back to the normal (2T2C) operating mode.

  • Patent number: 8736354
    Abstract: An electronic device includes a bandgap reference voltage generation stage. The bandgap reference voltage generation stage comprises a device with a PN-junction, a current source feeding a first current during a first period of time and a second higher current during a second period of time through the PN-junction. The bandgap reference voltage is generated from a combination of a first voltage drop across the PN-junction during the first period of time and a second voltage drop across the PN-junction during the second period of time. This bandgap reference voltage is formed using switched capacitors.
