  • Publication number: 20190094079
    Abstract: An apparatus includes a temperature measurement circuit. The temperature measurement circuit includes a bandgap circuit including an amplifier having an offset voltage that is compensated by using a set of trimming bits. The bandgap circuit provides first and second voltages related to a temperature to be measured. The temperature measurement circuit further includes a measuring circuit coupled to receive the first and second voltages. The measuring circuit further includes a comparator coupled to receive the first and second voltages, wherein the measuring circuit derives a temperature measurement from the first and second voltages.

  • Publication number: 20180348805
    Abstract: Embodiments of bias current generator circuits are provided herein for generating stable bias currents. In one embodiment, a bias current generator circuit may include a voltage-to-current generating circuit, an integrate and hold circuit, an amplifier circuit and a plurality of output branches. The voltage-to-current generating circuit may supply a first current to a first node of the bias current generator circuit. The integrate and hold circuit may receive a second current, which is equal to a difference between the first current and a reference current, from the first node and may generate a first voltage in response thereto. The amplifier circuit may receive the first voltage generated by the integrate and hold circuit, and may generate a second voltage in response to the first voltage. The plurality of output branches may receive the second voltage, and may generate a plurality of bias currents in response thereto.
