Dynamic content placement for content delivery networks
Techniques are described for enabling a content delivery network (CDN) service of a cloud provider network to place content distributions across points of presence (PoPs) within a common geographic area in a manner that makes efficient use of the resources provided by the PoPs.

The DNS service uses the log data to periodically generate characterization data for the distributions (e.g., in terms of requests per second, bytes transferred per second, and cache width usage). The DNS service uses the generated characterization data to assign particular distributions to particular PoPs of each PoP group such that the distributions are distributed across the PoPs according to the characterization data. The DNS service uses the assignments to generate routing data used by the DNS service to resolve DNS queries for particular distributions to particular PoPs of PoP groups. |

Low-power programmable bandwidth continuous-time delta sigma modulator based analog to digital converter
A continuous-time (CT) delta-sigma modulator (DSM) based analog to digital converter (ADC) in a radio receive chain supports a wide range of data rates in a power efficient way in a small die area.

With the negative-R assistance disabled, loop-filter resistor values are increased, instead of only the loop filter capacitor values to scale the noise transfer function (NTF), thereby limiting the capacitor area needed and enabling lower power operation. The NTF zero location is programmable allowing the NTF zero to be located near the intermediate frequency for different bandwidths to reduce the DSM quantization noise contribution for narrow-band (low data rate) applications. |
