Abstract: The techniques of this disclosure can cancel or reduce the kT/C noise directly before the gain stage. The effect of the kT/C noise can be greatly reduced, allowing both lower noise conversion and smaller sampling capacitors, which can reduce the die area and reduce the power consumption of the ADC.

Abstract: A Management-as-a-Service (MaaS) agent running on a client network creates a reverse session-origination (RSO) tunnel between the client network and a MaaS server. The MaaS agent collects client statistics at and regarding the client network and transmits the client statistics to the MaaS server. The MaaS server analyzes the client data and sends alerts or other messages to a user, who may be outside the client network, in the event certain conditions are met.

Abstract: Comparator input noise or offset suppression can include an error detector circuit that can operate in a feedback loop, such as during an autozero phase. The error detector circuit can include a time-varying filter response to improve accuracy and convergence time. The comparator can be used in a successive approximation routine (SAR) or other analog-to-digital converter (ADC) circuit, such as to control a digital-to-analog converter (DAC), such as can be used to adjust a tuning circuit within the comparator to compensate for noise or offset. The DAC can be combined with a DAC used for carrying out SAR bit-trials or bit decisions.

Abstract: Noise sources in an ADC circuit can include kT/C noise of a sampling capacitor, noise coupling on to sampling capacitors from digital circuits, and amplifier noise. Also, charge injection from mismatch in sample switches can cause offsets. These various noise sources can be largely canceled or reduced using described techniques. As a result, the size of the sampling capacitors can be greatly reduced, while still achieving significantly improved noise performance and power efficiency for the overall converter.

Abstract: Various background calibration techniques to calibrate inter-stage gain, e.g., in pipelined ADCs, are described to allow open loop amplifier circuits to be used as residue amplifiers for better power efficiency. Using various techniques, a well-controlled perturbation can be injected between two conversions and the actual perturbation after a residue amplifier can be measured. By comparing the actual measurement against an expected value, the gain information of the residue amplifier can be estimated and then calibration can be applied.

Abstract: Techniques that allow application of noise-shaped dither without applying dither at sampling, resulting in the analog-to-digital converter (ADC) circuit advantageously being balanced during acquisition.

Abstract: A Management-as-a-Service (MaaS) agent running on a SOPS creates collecting management statistics relating to the health, utilization, and performance of a subscriber on-premises system (SOPS). The MaaS agent forwards the collected data to a MaaS server, which stores the data in association with a tenant identifier (TID) in a multi-tenant database. The MaaS server tags user queries with the TID, so that the query result is based on management data for the respective SOPS, to the exclusion of SOPS associated with different TIDs. The use of multi-tenant techniques with non-multi-tenant SOPS allows one MaaS to manage plural SOPS while maintaining isolation of the management data for the respective SOPS. In addition, the use of multi-tenant techniques allows SOPS to be managed together with cloud-based subscriber applications, facilitating common management of hybrid cloud and on-premises systems.
