Powering Analog circuit through SMPS.

SMPS output has ripple and switching noise at its output. Such a supply could hamper performance of high resolution slow speed analog circuit.How to reduce it? A low noise linear regulator would do? An LC filter can work or both( LC filter followed by linear regulator)? A ferrite bead is also a general practice."Please suggest me how should i power my slow speed high resolution analog hardware(i am talking about process control, mainly temperature measurement applications)".

  • Powering Noise Sensitive Systems
    When it comes to high performance signal chains, you need high performance power solutions. Noise sensitive circuits such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), amplifiers, and phase lock loops (PLLs)—as well as FPGAs—demand low noise power supplies that require specialized design techniques. Engineers spend hours trying to figure out how to power these circuits without adding noise. This presentation will focus on understanding various methods for not only approaching but meeting system requirements. The session will introduce tested solutions and layout considerations that must be taken into account when designing with switching regulators and low drop out (LDO) regulators.
