AbstractThis paper studies how nonlinear distortion is generated in the combination of an inverter-based low-noise amplifier and a passive mixer. The dominant nonlinearity appears to be the quadratic $$V_{gs}V_{ds}$$ V gs V ds mixing term in the passive mixer that first causes low-frequency IM2 and then upconverts it to IM3. Adding a common-mode feedback (CMFB) cancels the IM2 in a pseudo-differential structure, and hence also reduces the IM3 caused by the cascaded second order nonlinearities significantly. The effect of CMFB gain, bandwidth and linearity were analyzed, and it is concluded that from the linearity point of view, the feedback circuit does not have to be very wideband since the dominant distortion products originate from baseband. Finally, the paper takes a look at the spurious tones rising in the mixing, and how to extend the analysis to include the actual frequency translation effect.

Current observational results for the abundances of the very heavy elements (Z>30) in Population II halo stars are reviewed. New high resolution, low noise spectra of many of these extremely metal-poor stars reveal general consistency in their overall abundance patterns. Below Galactic metallicities of [Fe/H] Ã −2, all of the very heavy elements were manufactured almost exclusively in r-process synthesis events. However, there is considerable star-to-star scatter in the overall level of very heavy element abundances, indicating the influence of local supernovas on element production in the very early, unmixed Galactic halo. The s-process appears to contribute substantially to stellar abundances only in stars more metal-rich than [Fe/H] Ã −2.
