Steven Terryn, Dieter Joos: Bandwidth calibration of active filter. STMicroelectronics Belgium, Lisa K Jorgenson, James H Morris, Wolf Greenfield & Sacks P C, April 6, 2010: US07692484 (3 worldwide citation)

An active RC filter has an op-amp and a biasing circuit arranged to bias the op-amp to set a gain bandwidth product of the op-amp according to a desired pole frequency of the filter. The biasing circuit is operable according to an output of an RC calibration circuit. The op-amp can be an OTA transco ...

Wouter Aerts, Roland Hug: Sample selector time domain interpolation. STMicroelectronics Belgium, Lisa K Jorgenson, James H Morris, Wolf Greenfield & Sacks P C, January 27, 2009: US07482953 (3 worldwide citation)

A signal resampler carries out a time domain interpolation of an input signal for compensating for frequency offset, such as found in an ADSL system. A sample selector interpolator carries out part of the interpolation and a second, e.g. polynomial interpolator carries out the rest of the interpolat ...
