In an example, a temperature-compensated voltage reference circuit includes a current mirror portion and a temperature-compensated output portion coupled to the current mirror portion. The temperature-compensated output portion comprises a very low threshold voltage (Vt) transistor coupled in series with a negative temperature coefficient transistor. The output portion can further include a positive temperature coefficient element coupled in series with the very low Vt transistor. The positive temperature coefficient element can be an adjustable resistive element. The output portion can further include an output transistor having a gate coupled to the current mirror portion and coupled between a supply voltage and the positive temperature coefficient element. The very low Vt transistor can be a substantially zero Vt n-channel metal-oxide-semiconductor (NMOS) transistor, and can be coupled in a diode configuration.

  • Publication number: 20120216084
    Abstract: A system involves a first SerDes link from a first integrated circuit (IC) to a second IC and a second link from the second IC to the first IC. Power consumption settings in circuitry of the first link are adjusted to control power consumption such that the bit error rate of the first link is maintained in a range, where the lower bound of the range is substantially greater than zero. Power consumption settings in circuitry for the second link are adjusted to control power consumption such that the bit error rate of the second link is maintained in range, where the lower bound of the range is substantially greater than zero. In one example, circuitry in the second IC detects errors in the first link and reports back via the second link. The first IC uses the reported information to determine a bit error rate for the first link.

  • Publication number: 20120151299
    Abstract: Apparatuses and methods for low power combined self-refresh and self-correction of a Dynamic Random Access Memory (DRAM) array. During a self-refresh cycle, a first portion of a first row of the DRAM array is accessed and analyzed for one or more errors, wherein a bit width of the first portion is less than a bit width of the first row. If one or more errors are detected, the one or more errors are corrected to form a corrected first portion. The corrected first portion is selectively written back to the first row. If no errors are detected in the first portion, a write back of the first portion to the first row is prevented.
