  • Patent number: 9853560
    Abstract: Congruent power and timing signals in a single electronic device. In an embodiment, a circuit may include just one isolation transformer operable to generate a power signal and a timing signal. On the secondary side, two branches may extract both a power signal and a clock signal for use in the circuit on the isolated secondary side. The first branch may be coupled to the transformer and operable to manipulate the signal into a power signal, such as a 5V DC signal. Likewise, the second circuit branch is operable to manipulate the signal into a clock signal, such as a 5 V signal with a frequency of 1 MHz. By extracting both a power supply signal and a clock signal from the same isolation transformer on the secondary side, valuable space may be saved on an integrated circuit device with only having a single winding for a single isolation transformer.

  • Patent number: 8575994
    Abstract: A clock source is configured to provide an oscillating signal to be divided into a clock signal. A temperature sensor senses a first temperature of the clock source. The clock source is subjected to at least one second temperature implemented by a temperature alteration module. A calibration module calibrates the clock signal based on the at least one second temperature, the first temperature, a reference signal, and the oscillating signal at the at least one second temperature.
