App note from Littelfuse about automotive electrical noises and where they came from and what to do with them in order to prevent it from going to your circuit. Link here (PDF) As the control circuitry in the automobile continues to develop, there is a greater need to consider the capability of new technology in […]

App note: Phase noise measurement guide for oscillators
App note from SiTime about phase noise, its fundamental and going to actual measurements. Link here Phase noise is one of the fundamental metrics for oscillators. An experienced engineer can tell a lot about the quality of an oscillator and whether it fits the application by looking at the phase noise plot. RF engineers focus […]
App note: Power supply rejection for low-jitter clocks
Method of rejecting noises from power supply, an app note from Silicon Labs. Link here (PDF) Hardware designers are routinely challenged to increase functional density while shrinking the overall PCB footprint of each new design. One significant challenge is minimizing clock jitter through careful board design while meeting the design’s functional and space requirements. Since […]
App note: Noise sources in low dropout (LDO) regulators
Looking for a clean power supply for a sensitive analog circuit? Analog Devices describes the sources of noise in LDO voltage regulators, and provides some examples to limit and combat the noise. In general, LDO noise comprises two components: intrinsic, or internally generated noise, and extrinsic, or externally generated noise. Thermal and 1/f noise are […]
