Analog Filters in Nanometer CMOS (Springer Series in - download pdf or read online

By Heimo Uhrmann, Robert Kolm, Horst Zimmermann

Ranging from the fundamentals of analog filters and the negative transistor features in nanometer CMOS 10 high-performance analog filters built by way of the authors in a hundred and twenty nm and sixty five nm CMOS are defined largely. between them are gm-C filters, current-mode filters, and lively filters for system-on-chip recognition for Bluetooth, WCDMA, UWB, DVB-H, and LTE purposes. For the lively filters numerous operational amplifier designs are defined. The e-book, in addition, encompasses a evaluation of the most recent kingdom of analysis on low-voltage low-power analog filters. to hide the subject of the e-book comprehensively, linearization concerns and size equipment for the characterization of complex analog filters are brought furthermore. quite a few intricate illustrations advertise a simple comprehension. This e-book could be of worth to engineers and researchers in in addition to scientists and Ph.D scholars at universities. The ebook is additionally recommendable to graduate scholars specializing on nanoelectronics, microelectronics or circuit engineering.

So the closed-loop common-mode gain must be smaller than 1.

The architecture of the realized filter [57] is shown in Fig. 17. For two transconductors (Gm0 , Gm2 ) a digitally programmable concept was developed. 10)). In the Figs. 19(b) the chip photograph and the layout plot of the realized filter are shown. All capacitors were realized as metal-metal capacitors. The chip area of the whole chip is 850 µm × 550 µm, the chip area of the filter is 270 µm × 140 µm. 5 V. 20 shows the measured DC transfer characteristics for the case of minimum and maximum gain.

The main disadvantage of FOM 1 is that it is finally independent of the cut-off frequency because the integrated noise and so the DR depend on the cut-off frequency. Another drawback is also that the DR depends on the filter capacitances and so on the chip area which does not play a role in this FOM. 3) where SFDR is the spurious free dynamic range, IIP3 is the 3rd-order input intercept-point and A is the area of the filter. In general, the SFDR represents the maximum relative level that a circuit can tolerate while producing an acceptable signal quality from a small input level.
