The Time Has Come

Posted on 02 August 2012

      Piezoelectric MEMS Oscillators for Industrial Frequency Control An accurate oscillator lies at the ticking heart of all digital electronics, from consumer multimedia products to industrial automation and monitoring systems, networking and communications infrastructure, and rugged military equipment. Historically, engineers have exploited the resonant properties of quartz to support accurate timing. Unrelenting pressure [...]

Enhancing Power Supply Rejection Ratio for Low-Jitter Clocks

Posted on 29 June 2012

      Highly immune technology to external noise is an effective way to avoid design problems Today's electronic systems require advanced design from top to bottom. Cost and performance optimization is important in all applications, and power delivery and noise coupling concerns are as critical as ever. With jitter budgets tightening, advanced mixed-signal clocking [...]

Crystal Oscillator Design and Negative Resistance

Posted on 01 September 2006

      Active elements must be able to function with crystals of varying parameters There is a discrepancy, however, in the measured negative resistance in comparison to the simulated start-up negative resistance. Differences in signal and impedance levels coupled with circuit nonlinearities are a major part of the measurement discrepancy. By Anthony M. Scalpi, [...]
